Custom Onyx Vanity Tops in Boise
Cultured stone vanity tops made to your exact measurements, with the sink molded right into the top, no seams, no caulk lines, no grout, and a lifetime warranty on the stone.
One solid piece, sink and all
A drop-in sink sits in a bead of caulk that collects grime and eventually fails. An Onyx vanity top is different: the bowl is part of the top itself, molded as a single solid piece of cultured stone.
- Integrated sinks no rim, no seam, no caulk line where the bowl meets the counter
- Made to size built for your exact cabinet, wall-to-wall, any faucet layout, single or double bowl
- Effortless cleaning wipe the whole surface in one pass; nothing to reseal, ever
- Real cultured stone color and material run all the way through, backed by a lifetime warranty
- A wide palette of Onyx colors and finishes to match your shower walls or stand on its own
The upgrade that finishes any remodel
Most homeowners add a vanity top while we're already there for a bigger project, same crew, same visit, one clean result.
