Onyx Collection is a USA-made solid-surface shower system — custom-fabricated to fit your exact bathroom dimensions. It's not a tile installation, and it's not an acrylic liner placed over an existing surface. It's a complete, purpose-built shower system designed to look exceptional and require almost no maintenance.
Onyx Collection is a solid-surface material — a manufactured composite that looks and feels like high-end stone, but is non-porous and custom-fabricated for each installation. Unlike tile, there is no grout. Unlike acrylic liner systems, it's not placed over an existing surface — it's a complete replacement system with its own walls, base, niches, and accessories.
Each Onyx installation begins with measurements taken at your home. The panels are fabricated in the USA to those exact dimensions — not cut from standard panels and adapted to fit. This means truly custom fit and finish, with seams only where the design calls for them, not where the stock size happened to end.
Onyx Collection isn't just shower wall panels. It's a complete system:
Onyx Collection's lifetime warranty is available through authorized dealer installation. Installation by an unauthorized contractor can void warranty coverage. It also matters for the quality of the installation itself — an authorized dealer has the product knowledge, training, and installation experience to correctly measure, order, and install the system.
Minnesota Home Improvements has been an authorized Onyx Collection dealer since 1975 — one of the longest-tenured dealers in Minnesota. We have installed Onyx in thousands of Minnesota bathrooms across every home type, age, and configuration. We know the product well enough to tell you honestly what it's the right choice for, and what it isn't.
Minnesota's water supply is among the hardest in the Upper Midwest. Much of Central Minnesota — St. Cloud, Brainerd, Willmar — draws water from aquifers with high calcium and magnesium content. Even in the Twin Cities metro, water hardness is substantial enough that tile grout maintenance is an ongoing commitment for homeowners with tiled showers.
Hard water minerals are absorbed by porous tile grout. Over time, they create staining that won't clean off with standard cleaners. The mineral deposits also expand and contract with temperature changes, accelerating the cracking and loosening of grout that eventually leads to water getting behind the tile surface. The annual ritual of re-caulking corners, sealing grout lines, and trying to keep the shower looking clean is a direct consequence of this combination of hard water and porous surfaces.
Onyx Collection solid-surface panels are non-porous. Calcium and magnesium deposits sit on the surface rather than being absorbed into it. They wipe off with a damp cloth rather than building up into permanent staining. There are no grout lines to absorb, crack, or require annual maintenance. For Minnesota homeowners who have spent years dealing with hard water grout problems, this is not a small quality-of-life improvement — it's a meaningful, daily difference every time they step out of the shower.
Beyond the practical case, Onyx is also simply a better-looking product than fiberglass or acrylic liners in most applications. The solid-surface material has depth and character that sheet acrylic doesn't. The custom fit means no awkward seams or gaps. The range of colors and patterns — from clean white to marble-look and stone textures — gives homeowners real design choices rather than a selection of generic white or almond stock products.
Onyx Collection is a USA-made solid-surface shower and bath system. It is custom-fabricated to your exact bathroom dimensions — not cut from standard-size panels to fit your space. The material is non-porous, with no grout lines anywhere in the installation. It's available in dozens of colors and patterns and carries a lifetime product warranty when installed by an authorized dealer like Minnesota Home Improvements.
They're different products with different strengths. Onyx wins on maintenance: no grout to seal, scrub, replace, or re-caulk, and a non-porous surface that resists the hard water mineral deposits that are a genuine problem in Central Minnesota. Tile offers more material variety and a traditional aesthetic. For homeowners who want a beautiful shower they won't need to maintain annually, Onyx is the better practical choice in Minnesota's hard water environment.
Onyx is non-porous solid surface — a substantially different material from acrylic. Bath Fitter and similar systems install a thin acrylic shell over your existing shower walls, which means you're layering over whatever is already there. Onyx is a full replacement system — the old surface comes down (or in many cases can be installed over tile), and a custom-fabricated Onyx system goes in. The appearance is higher-end, the customization options are broader, and the material has more substance. Both eliminate grout lines, but the product feel and longevity differ meaningfully.
We bring samples to your home during the free in-home consultation — no showroom visit required. This is standard practice for all our consultations. You evaluate colors and patterns in your own space, in your own lighting, next to your existing flooring and fixtures, before making any decision. There's no cost and no obligation to the consultation.
Yes — Onyx Collection offers a lifetime product warranty available through authorized dealer installation. Minnesota Home Improvements / Minnesota Bath Renewal has been an authorized Onyx Collection dealer since 1975. We register your installation for warranty coverage as part of the project. If a warranty issue arises after installation, we handle it — you're not navigating manufacturer claims on your own.
