THE FIX
Considering a New Tub Surround?
Plan it right and the rest follows.
"Won't water get under it?"
✓ Go Undermount.
The tub goes under the slab, not on top of it. Water wipes back into the tub the way it does with an undermount sink, so nothing puddles on a raised lip.
"What if the tub needs service later?"
✓ Plan the Access.
Get the access panel planned before anything is fabricated. Sometimes it lands in an adjoining closet, and sometimes we waterjet a removable piece into the slab itself.
"What happens to the piece you cut out? "
✓ Use the Cutout.
It doesn't have to go to waste. Planned early, that piece becomes your vanity top, a shower seat, or niches.

Materials
Best Tub Surround Materials
Granite
Natural, hard, and nothing a bathroom does bothers it. The color range runs from soft and light all the way to full exotics, so the stone can be the showpiece.
Quartz
Engineered, so it flexes where natural stone would snap. It's the material we're most comfortable handling on a big one-piece deck with no seams.
Quartzite
The marble look in a tougher natural stone, with colors from soft whites to heavy, dramatic patterns.
Marble
Marble gets an easier life in a bathroom. No cooking acids, no cutting boards, just water and bath products. It's the look most homeowners have in mind when they picture a stone tub.
Soapstone
A familiar material in a new place. Porcelain has covered floors and walls for years, and now it comes in slabs big enough for counters. Nothing soaks in, nothing etches, and it never needs sealing.
Porcelain
Naturally non-porous and matte, and it deepens into a warm patina over time. Rarely seen in a bathroom, so it's a tub surround nobody else has.

What We Do
We Don't Stop at the Countertop
Pricing
How Much Do Tub Surrounds Cost?
Pricing matters. It's the first question everybody asks, and we get it
But there's no price list in this business. Two suppliers can charge different prices for the same slab, and the work you want done changes the rest of it.
A tub surround is priced by the square foot, like any counter. About 95% of materials fall between $55 and $150 per square foot installed. A few always run above it: Blue Bahia granite, Blue Macaubas and Cristallo quartzites, the Calacatta and Statuario Italian marble families, and Onyx.
But it's not just about material. Here's what else affects your price:
- Sourcing: When your material is already in our inventory, you pay a set price per square foot for the footage you use. If it's something we don't stock, we bring it in from our suppliers, and slabs come whole, since that's how the industry sells them. Different suppliers price the same slab differently, so we shop for the best value, and we keep remnants on hand for small projects.
- Project size: Bigger projects cost more than smaller ones, but often get better per-square-foot pricing.
- Complexity: Waterfall sides mean mitered corners and more fabrication. A skirt down the tub sides adds pieces. An integrated sink in the vanity adds work. A thicker built-up edge or a bench adds more. Each one adds cost.
- One piece or several: A one-piece deck needs a slab big enough to cover the whole tub. Once the opening is cut out, what stays is a frame around eight to ten inches wide, and the rest leaves as one large cutout. Building it in pieces uses far less material. The trade is the look.
- Waste: We lay out every cut digitally to get the most out of each slab, and we plan that cutout into a vanity top, a shower seat, or niches wherever it works. On a heavily veined stone the pattern still decides how the piece comes out. Beautiful, but it comes at a cost.
- Supply and demand: Desirability drives price. What's trendy costs more and what's out of fashion costs less. The rare blues are expensive because they're naturally rare, and the Italian marbles because of high demand and limited supply.
Comparing Quotes?
The service side of a quote, meaning templating, fabrication, edge work, and installation, runs about $30 to $50 per square foot, and it's fairly consistent across the industry. The big difference between quotes is almost always the material itself.
Two things to watch for: a quote that isn't itemized, where any change becomes an extra, and "free edge" promotions, where the cost is built in somewhere else. If one quote comes in far lower, you're usually looking at a different material or brand, not a better deal.
Our quotes spell it out line by line: template, fabrication, edge profile, the tub cutout, and installation, so you can compare apples to apples. And it helps to like more than one color, because flexibility is what lets you land on budget.
So How Do You Budget?
Don't shop by material name. Shop by color and look. Come to our warehouse in Southborough, see, touch, and feel your options, and choose what fits your budget.
