Total Duration :

3 Months

Six shower outlets, one continuous stone field, and a tub with nothing behind it but light. That was the brief, and it set the whole sequence. We took the room to studs, relocated supply and waste, roughed in a multi-outlet valve manifold, then waterproofed the full wet zone before any stone touched a wall.

Quiet was the design goal, in a room with a lot of hardware in it. Warm onyx-veined porcelain runs floor to ceiling so the eye reads one surface instead of a grid, and every valve, sconce, and shelf was set to that layout rather than fighting it. Chrome stays the only other material in the room.

The result reads as a spa rather than a bathroom, cleared inspection under our California license, and closed in just 3 months with our team standing behind every detail long after the final walkthrough.

Nothing here was allowed in that did not earn its place. The tub alcove holds a floor-mount filler, a floating stone shelf, and four sconces, and that is all. No towel bar, no shelf clutter, no pattern break in the stone behind it.

Detail work carried the wet zone. A fabricated stone bench runs the shower’s short wall at seated height, the curb was cut and mitered from the same material, and the pan is small-format mosaic set to a central point drain so slope is achieved without cutting large panels into wedges. The niche was framed and waterproofed during rough-in, then trimmed with a stone shelf that matches the field.

Handover included a pressure-tested valve system, a balanced exhaust fan, and a documented punch list closed inside a week.

What This Bathroom Took

A room this quiet takes more coordination than a busy one. Three things carried it.
Valve and Manifold Rough-In

Valve and Manifold Rough-In

Six outlets share one supply system, so pressure balance, valve depth, and outlet height were laid out and pressure-tested before a single panel went on the wall.

Large-Format Panel Layout

Large-Format Panel Layout

Panels were dry-laid and sequenced so the veining runs continuously and the cuts land at corners rather than mid-wall, which is why the room reads as stone instead of tile.

Fabricated Stone Bench and Curb

Fabricated Stone Bench and Curb

The bench, curb, niche shelf, and floating shelf were all fabricated from the field material, keeping the room to one visual note instead of introducing a trim piece.

 Frequently Asked Questions

How long does a primary bathroom remodel take?

This project ran 3 months from demolition to final walkthrough. Most full primary bath remodels land between 10 and 14 weeks. Stone fabrication, custom glass, and fixture lead times usually set the schedule, so we order early and sequence demolition against confirmed delivery dates.
