Bathroom Renovation & Remodeling

Custom Tile. Frameless Glass. Freestanding Soakers.

A bathroom renovation takes the tub or shower, tile, vanity, and fixtures down to framing and subfloor, then rebuilds the room with new waterproofing, plumbing, ventilation, and finishes, normally under a city permit. Paragon Home Services renovates primary suites, hall baths, and tub-to-shower conversions across the South Bay, coordinating tile, glass, plumbing, and electrical under one contract. In Torrance, Redondo Beach, and Palos Verdes homes from the 1950s and 1960s, demolition regularly exposes cast-iron drains, galvanized supply pipe, and rotted subfloor around an old toilet or tub. We account for those possibilities before signing and water-test the shower pan before a single tile is set.

Bathroom Remodel Decisions That Matter Most

Our Bathroom Renovation Process

1. 01Walkthrough and measurements — we look at the existing shower, flooring, vanity plumbing, and ventilation, check access from the attic or crawlspace, and ask how the room gets used daily.
2. 02Design and selections — layout, tile, vanity, fixtures, glass, and lighting are chosen and documented, with tile quantities calculated before anything is ordered.
3. 03Fixed-price proposal and permit — you receive a written scope and price, and we file with your city building department for the plumbing, electrical, and any framing changes.
4. 04Demolition and repairs — the room comes down to studs and subfloor behind dust protection, and rotted framing, damaged subfloor, and failing drain or supply lines are replaced as found.
5. 05Rough-in and waterproofing — valves, drains, circuits, and fan ducting pass rough inspection, then the membrane system goes on and the shower pan is water-tested.
6. 06Tile, vanity, and fixtures — floor and wall tile, niches, and benches are set, followed by the vanity, countertop, toilet, trim, and mirrors.
7. 07Glass, final inspection, and walkthrough — the enclosure is measured off the finished tile and installed, the inspector signs off, and we review every detail with you.

Bathroom Remodels — Frequently Asked Questions

How much does a bathroom remodel cost in the South Bay?

Here are realistic South Bay ranges for 2026. A tub-to-shower conversion or hall bath update that keeps the plumbing where it is often runs $20,000 to $40,000. A full hall bathroom gut with new tile, vanity, and fixtures commonly falls between $40,000 and $70,000. Primary suite renovations with a large custom shower, double vanity, freestanding tub, and heated floors generally run $70,000 to $130,000 and up. Tile size and pattern, glass, fixture selections, moving the toilet or shower drain, and hidden damage behind old tile move the number most. Paragon provides a fixed quote after seeing the room in person.

How long does a bathroom remodel take?

Once construction starts, a hall bathroom typically takes about three to five weeks and a primary suite about five to eight weeks. Tile work cannot be rushed: waterproofing, mortar, and grout each need cure time, and inspections happen on the city's schedule. Custom glass is measured only after the tile is finished, which adds a short wait at the end. Before construction there is time for selections and permit review. If the house has a single bathroom, tell us at the estimate so we can sequence the work to keep the days without a usable shower to a minimum.

Can you convert my bathtub into a walk-in shower?

Yes, and it is one of the most common bathroom projects we do in the South Bay. The tub comes out, the drain is relocated for a shower pan, the valve is replaced and raised, and the walls and floor are waterproofed before tile. A standard 60-inch alcove converts into a generous shower with room for a niche and often a bench. The pan slope has to be right or water pools in the corners. If this is the only tub in the house, weigh that against how you use the home and who might buy it before committing to the change.

Do I need a permit to remodel a bathroom?

If the work replaces a shower valve, relocates a drain, adds circuits or an exhaust fan, or changes framing, a permit is typically required. Like-for-like swaps such as a new faucet or vanity top usually are not. Each South Bay city runs its own building department, and areas like San Pedro, Harbor City, and Westchester fall under the City of Los Angeles. Permitted work means the plumbing and electrical, and in many cities the shower pan, are inspected before they are covered up, which protects you at resale. Paragon files the permit and meets the inspector at each stage.

What is the best waterproofing for a tile shower?

A continuous membrane system installed to the manufacturer's instructions is the most reliable choice. Sheet membranes such as Schluter-Kerdi and foam board systems such as Wedi bond directly to the substrate with sealed seams, preformed corners, and a matched drain, so there is no gap for water to find. Liquid-applied membranes also perform well when built up to the specified thickness. Traditional mortar beds over a vinyl liner can last, but they hold water in the mortar and are prone to mildew and slow leaks. Whatever system is used, the pan should be water-tested before tile, since a mistake is invisible afterward.

Should I choose a curbless shower?

A curbless shower looks clean, removes a trip hazard, and keeps the bathroom usable if mobility changes later. The tradeoff is structural. The floor has to be recessed so the shower slopes to a linear or center drain without water escaping into the room. Over the raised wood foundations common in older Torrance and Redondo Beach homes, that usually means lowering the subfloor between joists. On a concrete slab it means cutting and re-pouring a section. We confirm the foundation type and joist direction before design, so you know whether curbless is simple or a meaningful added cost.
