1. Easy installation and labor savings
Walls come as four large panels, 84 inches tall, in widths of 24, 30, 32, and 36 inches. A full shower is one base plus four panels.
No tile setting, no grouting, no grout curing time.
Bases are pre-sloped to the drain, so there is no mortar bed or slope to build by hand.
Panels trim with a standard tile saw or circular saw and drill with a diamond or masonry bit. That lets them adapt on site to niches, windows, pony walls, and shower doors.
DIY friendly for experienced DIYers, with step-by-step installation videos on castico-tx.com.
Hiring out? Fewer steps means fewer labor hours on the invoice. Homeowners can find an installer near them at castico-tx.com/castico-remodeler-referral/.
Say it: A tile shower means hundreds of pieces, grout, and days of curing. CASTICO walls go up as four big panels over a pre-sloped base, so most of that labor simply isn't there.
2. Savings and simplicity with a combo shower kit
A combo shower kit includes the base, four wall panels, a matching glass door, a shower niche, and a drain plate.
Everything ships together on one pallet, which saves on shipping costs and time compared with ordering pieces separately.
Every component is designed to match, so there is no guessing whether the door, niche, or hardware will fit or coordinate.
The matching glass door is only available as part of a combo kit.
Combo kits come in 32x60 and 36x60, with 4 hardware finishes: brushed gold, brushed nickel, chrome, and matte black.
Say it: The combo kit is your whole shower on one pallet: base, walls, glass door, niche, and drain plate. It saves on shipping, everything matches, and it just makes the project easier.
3. Industry-leading thickness and quality
Wall panels are an industry-leading 1/2 inch thick, far thicker than typical acrylic and fiberglass surrounds.
Made from a proprietary blend of crushed quartz, marble, and granite bonded with resin. It is solid composite stone through its full thickness, not a thin shell over a backer.
Non-porous, so it does not absorb water.
Bases handle 115 lbs per square inch when fully supported. That's roughly an 8,280-pound person standing on one foot.
Lighter than natural stone, so it is easier to carry and install.
Built to tight tolerances: 1/8 inch on all dimensions, 1/16 inch on pattern alignment.
Say it: Our walls are an industry-leading half inch of solid composite stone, made from real crushed quartz, marble, and granite. It feels like stone because it's made from stone.
4. Top tier designs at an affordable price
15 wall designs, including Subway and White Waves patterns.
4 base colors: Carrara, Black Onyx, Graphite, and White.
4 hardware finishes on kits: brushed gold, brushed nickel, chrome, and matte black.
The look of natural stone and tile with no grout lines breaking up the design.
Wall panels can also be used outside the shower as decorative wall cladding elsewhere in the bathroom.
Say it: You get a high-end stone look with clean, grout-free walls, without paying custom stone prices.

6. Curbless and ADA accessible
Every CASTICO base is curbless, so there is no step up into the shower.
Installed flush with the floor, any CASTICO base can be ADA accessible, including for wheelchair roll-in access.
Ideal for aging in place, accessibility remodels, and anyone who wants a modern, open, zero-entry look.
Wet DCOF of 0.55 gives secure footing, similar to rubber on wet cement.
Full ADA compliance for a bathroom also depends on the rest of the installation, such as grab bars, clearances, and controls.
Say it: All of our bases are curbless, so installed flush with the floor, they can be ADA accessible. No step, no curb, just walk or roll right in.
7. Adds real value to your home
An updated bathroom is one of the first things buyers notice when touring a home.
A stone-look, grout-free shower reads as a premium upgrade, not a basic replacement.
Certified to the Uniform Plumbing Code, which supports permitted, inspected remodels and new builds.
Low maintenance keeps it looking new for years, which protects the value of the upgrade.
Say it: A CASTICO shower looks like a custom stone job, which is exactly what buyers remember when they walk through a home.
8. Low maintenance, no grout
No grout lines to scrub, stain, crack, mildew, or reseal.
The non-porous surface cleans with a non-abrasive foaming tile cleaner and a microfiber cloth.
No sealing required. Sealer is optional and only makes cleaning easier and colors richer.
Say it: No grout means no scrubbing grout lines. A foaming cleaner and a microfiber cloth are all it takes.

Common objections
"Why not just tile?" Tile means hundreds of pieces, grout lines to maintain, and days of labor. CASTICO gives you the stone look in four panels with no grout.
"Acrylic or fiberglass is cheaper." CASTICO is industry-leading 1/2-inch solid composite stone made from real crushed quartz, marble, and granite. It looks and feels like stone, not plastic.
"Will it look fake?" It's made from crushed natural stone minerals, so the look and feel are stone. With no grout lines, the design reads clean and continuous.
"Can I install it myself?" Yes, if you're comfortable with a DIY project at that level. Installation videos are on castico-tx.com, and our installer referral map can connect you with a pro.
"How fast can I get it?" Orders ship within 3 business days, then typically arrive in 3–7 business days in the US.
"Is it durable?" The base handles 115 PSI when fully supported, the material is non-porous, and it's backed by a limited lifetime warranty.
Chatbot guidance
Keep replies short, positive, and light. Lead with one or two selling points that fit the question, not the whole list.
Do not quote prices. Direct shoppers to the product listing on homedepot.com.
Do not guarantee delivery dates. Shipping and transit times are estimates.
Do not say shower products are sold on castico-tx.com. They are sold at The Home Depot.
Do not offer custom sizes. They are not available.
Do not say the warranty transfers to a new owner. It does not.
On accessibility, say bases can be ADA accessible when installed flush with the floor. Do not say a product alone makes a bathroom ADA compliant.
When cleaning comes up, always mention that bleach should never be used on wall panels.
Only mention the sizes listed in this article.
