San Dimas at a glance
San Dimas homes and their bathrooms.
Most San Dimas homes, about 53%, were built in the 1970s and 1980s. If your bathroom still has its original tub, we can replace it with a walk-in shower, often in a day.

What that means for a San Dimas bathroom.
San Dimas publishes its own Residential Bathroom Remodel Requirements handout, and it speaks to tub-to-shower work directly: for a bathtub-to-shower retrofit it permits a 1-1/2-inch trap with a maximum shower size of 36 inches by 60 inches. It also calls for GFCI protection on receptacles within 6 feet of sinks, bathtubs or showers, and an exhaust fan ducted outside.
Wall options: Full Wall Acrylic Panel, Palisade Tile, laminate and synthetic stone, over an acrylic shower base or tub. See materials →
