Back to Onyx Certified Shower Installation

The Onyx Collection makes one of the best solid-surface shower products in the country, but it is only as good as the installer.

Onyx requires certified installers to keep their lifetime warranty intact. Many crews cut corners. We do not.

Hector has been installing Onyx for years and is factory-certified. You get the warranty, the look, and the install done right the first time.

1. Cost & Pricing Overview

Typical price range
$6,500–$14,000 installed in San Antonio

What affects the cost

  • Shower size and configuration (alcove, corner, walk-in)
  • Color and texture choice (premium textures cost more)
  • Niches, benches, shaving ledges, and trim accents
  • Whether plumbing rough-in moves
  • Glass enclosure type (separate quote, often paired)

When a quote is required

Onyx is custom manufactured, so price depends on the exact configuration. We provide a written bid after the on-site measure — no high-pressure same-day quotes.

3. Common Problems, Signs & Symptoms

If you're seeing any of these, it's probably time to call.

Previous shower failed shortly after install

Most premature failures trace back to a non-certified installer skipping steps. A certified install protects the warranty.

Big-box quote feels inflated

When the chain quotes Onyx, you're often paying for the salesman, the showroom, and a subcontractor. Going direct cuts out those layers.

Existing shower has constant maintenance issues

If you're constantly recaulking or scrubbing grout, an Onyx system eliminates both — no grout, no annual reseal.

Want a true lifetime warranty

Onyx's limited lifetime warranty is one of the strongest in the industry, but it is contingent on certified installation.
