Most people think a grout, mildew, mold, and germ-free, re-finishable, repairable, fashionable solid surface is an excellent value. I've installed quite a few and have never gotten a single callback or regret. Compared to other surfaces, I can't think of any downsides. Color/particulate/movement matching draining shelves aren't a problem.

We considered Swanstone but decided to do cultured granite because we needed a custom size, so CG was the least expensive way to do it. It performs identically to solid surface. We do have Swanstone counters in the kitchen, as well as a Swanstone integrated bathroom sink/counter, which were installed in 1990 and are as flawless now as they were the day after install.

We used the CG for both a custom neo-angle shower base and surround in the MBa, as well as the tub surround for the second bathroom. We have been EXTREMELY satisfied.

Caveats? Put in safety bars with the original design. The walls are slippery, especially when your hands or body are soapy. Squeegee or spray after every shower to avoid soap scum build-up, altho using liquid soap will cut that down to a minimum.

CG and solid surface vendors all offer inset shelving units. These tend to be shallow so plan carefully how many bottles users will be storing. We put in two shelving units in the neo-angle, one large one in the tub surround.

When in doubt about storage, more is always better!

I admire the beautiful tiled showers that people here install, but my DH and I agree if we ever move, we will put solid surface or CG into our next home, too. It is the single easiest thing to clean in our entire home.
