Send me the detailed estimateMost Portola Valley conversions are in the hall bath of a 1950s or 1960s ranch, where a 60-inch tub fills the alcove and nobody has used it in years. Over a crawlspace the drain can move to wherever the new shower needs it; on a slab section we keep the drain where it is or cut a shallow recess for a flat entry. Many owners want to stay in a single-story house on a hillside lot as long as they can, so curbless entries, a bench and grab-bar blocking are common requests, and we frame the blocking in even if the bars come later. In Portola Valley Ranch the conversion is interior work, and the only committee question is whether anything on the outside changes.
Neighborhoods we work in: Central Portola Valley, Westridge, Alpine Hills, Portola Valley Ranch, Corte Madera, Blue Oaks, Woodside Highlands, Los Trancos Woods, Vista Verde, Ladera.
The San Andreas fault runs through Portola Valley, and the town has mapped its ground since Resolution 500-1974, with a geologic map and a ground movement potential map that set building setbacks along the active traces. For a kitchen or bathroom inside the existing house, that rarely changes the job: the Town Geologist steps in for site development permits, foundation repair over 35 lineal feet, sites inside the fault setback or a flood zone, and additions over 500 square feet. It matters when a bathroom remodel turns into a bump-out, or when we open an old floor and find a cracked foundation, so we check the town’s maps for your parcel before we price anything structural.
Town of Portola Valley Planning & Building Department (765 Portola Rd, Portola Valley) issues permits in Portola Valley. Typical review time: not published by the town; we ask the Building Division for the current queue when we apply. We prepare the drawings, pull the permit under our license and meet the inspector at every visit; the fee is a line item on your estimate.
WestLight Energy (formerly Peninsula Clean Energy) supplies the power and PG&E delivers it. WestLight's rebates cover heat pump water heaters and heating, with a bonus for a panel upgrade done alongside them.
Two to three days for an acrylic wall system, about five working days for a tiled shower, and seven to ten for curbless. Permit timing is separate and depends on the town or the county.
If the valve or drain moves, yes: from the Town of Portola Valley, or from San Mateo County in Ladera and Los Trancos Woods. A like-for-like swap on the same drain sometimes does not; we confirm before quoting.
Usually. Over a crawlspace we lower the framing in the shower area; on a slab we cut a shallow recess. Either way the floor runs flat into the shower.
Not if another bathroom in the house keeps a tub. Families with small children look for one; the primary or second bath can be a shower.
