Newcastle Tub-to-Shower Conversion
1985 custom Newcastle home, 11×13 primary bath. Converted an unused garden tub into a 4×7 low-threshold walk-in shower along the longest wall, kept the rest of the bathroom intact, and replaced the swing door to the water closet with a pocket door.

A representative Newcastle conversion: 1985 custom home with a generous primary bath that included a separate water- closet room with a swing door, a garden tub on the longest wall, and a fiberglass corner shower. Plumbing was modern; the layout was the only thing dating the room.
What we changed
- Pulled the garden tub and reclaimed the entire long wall for a 4×7 walk-in shower
- Built the shower as low-threshold (1″ tile-clad curb) — the existing subfloor over a crawlspace made curbless impractical without joist work the homeowner didn't want to take on
- Replaced the WC swing door with a pocket door, gaining about 8 sq ft of usable space
- Tiled in 24×48 large-format sage stone-look porcelain on the walls with a smaller mosaic on the floor for slip resistance
- Installed a frameless glass enclosure with brushed brass CRL hinges, built-in horizontal niche, and end-of-shower bench
- Replaced the dated double oak vanity with rift oak floating cabinetry
Result
The primary bath reads modern but still belongs to the home — no jarring contrast with the rest of the house. Active build was five weeks; permit was pulled with Placer County.
