This article was researched using 9 sources. See our methodology and corrections policy.

An installed Onyx Collection shower typically costs $10,000 to $20,000, including the custom shower base, solid-surface wall panels, demolition, installation, plumbing, trim, and basic fixtures. A relatively simple replacement that keeps the existing footprint and drain location may cost $7,000 to $12,000. Larger showers with frameless glass, seating, accessibility changes, premium plumbing fixtures, or structural repairs can cost $20,000 to $30,000+.

The Onyx Collection does not publish one national retail price list. Its products are made to order and sold through independent dealers, so the final quote depends on the dimensions, color, finish, wall-panel configuration, base design, accessories, contractor markup, freight, and local installation rates. One estimate may cover only the Onyx products, while another includes the complete shower remodel.

The Onyx Collection is an engineered solid-surface bathroom product, not natural onyx stone. Its shower bases and wall panels do not require the recurring sealing, polishing, or color-enhancement treatments associated with porous stone.

The Onyx Collection says that every shower base, wall panel, trim piece, accessory, and lavatory product is custom-made to the buyer’s specifications and distributed through dealers. This dealer model is why two similar-looking projects can receive very different material and installation quotes.

One recent contractor guide places a basic professional Onyx replacement above $10,000, a common upgraded installation near $14,000 to $16,000, and more elaborate projects at $16,000 to $20,000+. Review the contractor’s Onyx shower pricing examples as regional context rather than a national rate sheet.

Homeowner reports show an even wider range. One buyer reported about $3,500 for the Onyx pan and surround and approximately $10,000 after installation, shower glass, and fixtures were included. Another homeowner received quotes from about $12,000 to more than $25,000. These reported Onyx costs are anecdotal and should be treated as low-confidence market signals.

What Onyx Collection Is

The Onyx Collection manufactures solid-surface shower bases, wall panels, tub surrounds, trim, seats, caddies, lavatory tops, and related bathroom products. The components can be ordered in custom dimensions and a variety of colors, finishes, and molded patterns.

The company’s material is made primarily from alumina trihydrate combined with a specially developed polyester resin. Its official material and product FAQ says alumina trihydrate is also a primary component in other solid-surface products. The resin creates the translucent appearance that inspired the Onyx name.

This material should not be confused with natural onyx, marble, granite, or another quarried stone. The old article’s references to stone quality grades, penetrating sealers, polishing services, and recurring color enhancement were incorrect.

Onyx wall panels are approximately 5/16 inch thick and have color throughout the material. Available finishes include gloss, matte, stone-tile patterns, subway-style patterns, shiplap, and other molded textures. The manufacturer states that its wall panels are not intended for steam-shower installations.

Base and Panel Costs

The shower base and wall-panel system usually accounts for the largest material expense. A conventional rectangular base with a standard drain location costs less than an oversized, neo-angle, dual-curb, ramped, or unusually shaped base.

The Onyx Collection can manufacture standard and custom bases with different curb profiles, drain positions, ramp configurations, and dimensions. This can be useful in older bathrooms where a standard fiberglass pan does not match the existing opening.

Wall cost depends on the width, panel height, finish, number of walls, cutouts, edge treatments, trim, window details, caddies, and whether the panels reach the ceiling. A basic alcove commonly uses one back panel and two side panels.

Ask whether the material quote includes:

• The shower base and drain components
• All wall panels and finished edges
• Corner and perimeter trim
• Color-matched silicone
• Recessed or surface-mounted caddies
• Freight and delivery
• Sales tax
• Onsite measurement
• Cutting or fabrication

ThePricer Project Math

Standard replacement: Assume $2,000 (about 1.7 full-time workweeks at $30 per hour) for a custom base, $3,500 for wall panels and trim, $2,500 for demolition and installation, $1,200 for plumbing, and $800 for fixtures and disposal. The complete project reaches $10,000.

Upgraded shower: Start with $6,500 in Onyx products. Add $4,500 for demolition, framing, substrate preparation, and panel installation, $2,000 for plumbing, $3,000 for frameless glass, and $1,500 for fixtures and permits. The total becomes $17,500.

Accessibility conversion: A custom ramped base and wall package costs a modeled $8,000. Add $6,000 for demolition, doorway and floor work, $3,000 for plumbing, $2,500 for glass, and $2,000 for a seat, grab bars, fixtures, and permits. The finished project reaches $21,500.

In the middle example, Onyx products account for 37.1% of the $17,500 bill. Labor, plumbing, glass, fixtures, and permits contribute the remaining $11,000. This explains why comparing panel prices alone does not reveal the real project cost.

General Shower Cost Context

An Onyx project should also be compared with the broader shower-remodel market. This Old House currently places a custom shower remodel around $8,500 to $10,000, depending on the materials, components, and project scope. Its 2026 shower cost guide also identifies moving drains and supply lines as one of the quickest ways to increase the total.

Angi reports that shower remodels can range from a few hundred dollars for limited updates to about $15,000 for larger overhauls. Its shower-remodel breakdown notes that material, shower type, enclosure, plumbing, and labor all influence pricing.

Onyx generally sits above inexpensive fiberglass or acrylic kits because it is fabricated to order. It can compete with custom tile or stone installations once waterproofing, wall preparation, setting labor, grout work, and project duration are included.

The Glass Enclosure

Glass is one of the most commonly omitted expenses in an Onyx quote. A contractor may describe a proposal as a complete shower while excluding the door or fixed glass panels.

HomeAdvisor currently places standard installed glass shower doors around $600 to $1,400, while high-end custom doors can cost $3,300 or more. Its glass shower-door pricing identifies size, thickness, hardware, height, shape, and customization as major cost factors.

A frameless neo-angle enclosure with multiple panels costs more than a basic framed sliding door. Extra height, low-iron glass, specialty finishes, protective coatings, unusual angles, and heavy hardware also increase the price.

The walls need appropriate framing or blocking where glass hardware will be anchored. Correct support is easier and less expensive to install before the Onyx panels cover the wall structure.

The Hidden Price

Demolition can reveal water damage, mold, deteriorated framing, corroded supply lines, an uneven subfloor, or an incorrectly installed drain. These problems may not be visible when the contractor prepares the first estimate.

Ask the contractor to state how concealed damage will be priced. The agreement should provide the hourly labor rate, material markup, approval process, and maximum amount that can be added without written authorization.

Other expenses commonly omitted from a material-only price include:

• Demolition and debris disposal
• Framing and subfloor repairs
• Drain or water-line relocation
• A new mixing valve
• Ventilation or electrical work
• Permit and inspection charges
• Glass measurement and installation
• Painting outside the shower
• Temporary bathing arrangements

Architectural Digest notes that bathrooms are among the most technically complicated rooms to remodel and recommends checking local permit requirements before beginning DIY work. Its bathroom remodeling guidance also warns that demolition can reveal structural repairs that were not obvious beforehand.

Supported Accessories

The Onyx Collection offers custom seats, corner caddies, recessed caddies, surface-mounted shelves, trim, crown molding, window trim, grab-bar backing, low-profile bases, and accessibility-oriented configurations.

A recessed caddy requires wall preparation and accurate cutting. A seat needs proper structural support and sealing. Grab bars must attach to structural blocking or another approved anchoring system rather than relying on the wall panel alone.

Plumbing fixtures are normally supplied by the dealer, contractor, plumber, or homeowner. A basic pressure-balanced valve and showerhead can cost a few hundred dollars, while thermostatic valves, handheld units, multiple outlets, body sprays, and premium finishes can add thousands.

Bluetooth sound systems, factory-built projector panels, integrated television screens, and illuminated wall slabs are not standard Onyx Collection offerings. Electrical lighting can be incorporated into the bathroom or shower ceiling when local codes and fixture ratings permit it.

Installation Requirements

Onyx Collection panels are often installed over properly prepared 1/2-inch sheetrock coated with latex primer. The substrate and the back of each panel need to be clean before adhesive silicone is applied.

The manufacturer provides instructions for bases, panels, trim, caddies, seats, and doors. Panels can be cut or trimmed with common woodworking tools, but the installer still needs accurate measurements, support, dry fitting, and careful seam preparation.

A solid-surface dealer explains that panel installations can sometimes be completed in one or two days once demolition, plumbing, wall preparation, and the base are ready. Its solid-surface installation overview should not be read as a guarantee that the entire bathroom remodel will take only two days.

The complete project may require one to four weeks when demolition, inspections, plumbing, repairs, glass fabrication, and other trades are included. Custom glass is commonly measured only after the shower walls and base are installed.

DIY or Professional Work

A skilled homeowner can install an Onyx system because the manufacturer publishes detailed installation instructions. A direct replacement with square walls, a sound subfloor, and an unchanged drain is easier than a curbless or accessibility conversion.

Large wall panels are heavy and difficult to maneuver in a confined room. Cutting the wrong opening or damaging a finished edge can require a replacement custom panel. A helper is usually needed to dry-fit and position the material safely.

DIY may fit when:

• The shower keeps its existing footprint and plumbing locations.
• The walls and floor are sound, level, and square.
• The homeowner has plumbing and finish-carpentry experience.
• The local permit requirements are understood.
• Help is available to lift and position the panels.

Professional installation is safer when:

• The drain, valve, or supply lines must move.
• The project requires structural or accessibility changes.
• Water damage is suspected behind the existing surround.
• Custom glass, windows, niches, or seating are involved.
• The household has only one working bathroom.

Accessible Shower Costs

The Onyx Collection can produce low-profile and ramped bases, but ordering one does not automatically make the entire bathroom accessible or ADA-compliant. The entrance, floor space, seat, controls, handheld spray, grab bars, enclosure, and surrounding room layout must work together.

The U.S. Access Board explains that accessible shower thresholds may be limited to 1/2 inch and that controls and enclosures cannot obstruct access to grab bars or shower fittings. Review its official bathing-room accessibility guidance when designing a commercial or standards-based accessible shower.

The federal ADA standards generally apply to public accommodations and commercial facilities, not automatically to every private residence. Residential aging-in-place design should be tailored to the person using the shower, local building requirements, and advice from qualified accessibility professionals.

Cleaning and Maintenance

Onyx Collection showers do not require penetrating natural-stone sealer. Routine cleaning is generally completed with a soft cloth, non-abrasive cleaner, or diluted white vinegar according to the manufacturer’s care guidance.

Abrasive powders, gritty pads, and harsh tools can dull or scratch the surface. The silicone seams should be kept clean and inspected for separation, cracking, or damage.

Failed silicone can allow moisture to reach the wall structure even though the panel itself is water-resistant. Replacing damaged sealant is ordinary shower maintenance, but it is not the same as sealing a porous stone slab.

The previous claim that owners should spend $200 to $500 every one to three years on professional polishing, sealing, and color enhancement was incorrect.

The Product Guarantee

The manufacturer promotes a “Yes, Guaranteed Forever” guarantee. Its published terms state that if an Onyx Collection product fails, the company will replace the product or refund its cost.

This should not be described as an unlimited remodeling warranty. It does not automatically promise payment for demolition, plumbing, glass removal, labor, hotel stays, water damage, or installation of a replacement panel or base.

Improper installation, unsuitable substrate, incorrect adhesive, structural movement, impact damage, and use of damaging cleaners may also require separate evaluation. Keep the original invoice, dealer name, product details, photographs, and installation records.

Onyx Versus Tile

Onyx panels eliminate grout joints across the main wall surfaces. This can reduce routine scrubbing and remove the need to repair, reseal, or recolor wall grout.

Tile provides a larger selection of patterns, materials, layouts, and individual design details. Basic ceramic tile may cost less, while natural stone, intricate mosaics, or large-format tile can cost as much as or more than an Onyx system.

Tile performance depends on the waterproofing system behind it. The tile and grout are not the shower’s only water-management layer. Onyx panels use fewer wall seams but still require correct substrate preparation and sealed joints.

Compare the complete Onyx quote with current tub-to-shower conversion costs rather than comparing only the price of wall coverings.

Comparing Other Systems

Acrylic and fiberglass shower kits generally cost less and can be practical for rentals, secondary bathrooms, or standard openings. Their dimensions, colors, shelf layouts, and base shapes are usually less customizable.

Bath Fitter pricing follows a different model based on acrylic liners, wall systems, and installation packages. It should not be compared with Onyx by wall-panel price alone.

Natural stone creates a different appearance but requires specialized fabrication, support, installation, and maintenance. The Onyx Collection brand name does not mean its care requirements match natural onyx.

Current shower valve replacement costs should also be included when an old valve is inaccessible, incompatible with new fixtures, or nearing the end of its service life.

Saving on Installation

Keeping the existing shower footprint, drain, valve, and supply lines in place can save thousands of dollars. Plumbing relocation and floor reconstruction often cost more than changing the panel color or finish.

Request at least three itemized estimates. Each quote should list the base, panels, trim, freight, demolition, substrate preparation, plumbing, fixtures, glass, accessories, permits, disposal, and warranty responsibilities.

Do not compare a materials-only dealer quote with a turnkey contractor quote. Mark each estimate with the costs that are missing and calculate the likely checkout total.

Choose upgrades based on daily value. A handheld shower, sound grab-bar backing, a stable seat, and an easy-to-use valve may provide more long-term benefit than body sprays or expensive glass hardware.

When Onyx Fits

An Onyx Collection shower may be worth considering if:

• You want custom dimensions without tiled wall grout.
• Easy routine cleaning is a priority.
• The bathroom needs a ramped or low-profile base.
• You prefer coordinated walls, base, trim, and accessories.
• The complete installed quote fits the remodeling budget.

Another system may fit better if:

• The primary goal is the lowest replacement price.
• A standard acrylic or fiberglass kit fits the opening.
• You want a highly detailed tile or mosaic design.
• The bathroom is likely to be remodeled again soon.
• The contractor will not provide an itemized estimate.
