Low profile shower bases are also available in custom sizes
Low Profile Shower Bases are often used when either: 1) stepping into high tub or over a tall shower curb is too difficult, or, 2) when a more contemporary look is desired.
Standard bases have radius corners and water channel webbing.
Standard Low Profile Curb height is 1 1/4” to 2 1/8” tall. All curbs have a slope back into the shower area and the shower area has a 1/4” per foot slope towards the drain.
Standard Low Profile Shower Bases are available individually and also as a kit with our Onyx wall panels. Other shower wall systems such as ceramic tile can also be used with Onyx shower bases.
Onyx Shower Kits can be ordered in 78”, 84”, 90”, 96”, 102”, and 108” tall heights (and any other height as needed – kit height includes base and walls). These kits include the shower base, all wall panels, adhesive silicone, and also color match seam-fill silicone.
