Why Costa Mesa ADU Builders Is Redlands’s Preferred Bathroom Remodeling Company
Our Bathroom Remodeling team works across Redlands constantly, and we’ve built a reputation around one thing: we open walls and find problems before they find you. Remodeling a bathroom in a 1920s Craftsman or a 1960s Loma Linda-adjacent tract home means dealing with wiring, drains, and framing that haven’t been touched in decades. Our crew knows what Redlands inspectors look for because we’ve pulled permits here, passed inspections here, and fixed the consequences of remodels done without permits here.
Led by Nate Calloway, our approach is inspection-first. Before we write a final contract, we open the areas that matter, scope what’s actually behind the tile and under the tub, and price the reality, not the brochure. Redlands homeowners tell us the same thing after the fact: the quote that looked higher up front was the one that didn’t grow halfway through. That’s not an accident. It’s the way we bid every job.
We also bring something most bathroom remodelers in Redlands don’t: full-scope construction capability. The same company that builds ADUs from shell to finish handles your bathroom, which means we can pull permits, run new electrical, frame, waterproof, tile, and trim without a single subcontractor handoff.
Our Bathroom Remodeling Services in Redlands
Full Bathroom Remodel
A full remodel in Redlands means gutting to the studs, replacing the shower or tub assembly, reworking the footprint if you want it, and finishing with new waterproofing, tile, fixtures, and lighting. We handle everything in one contract: demolition, framing repairs, plumbing, electrical, insulation, drywall, tile, glass, and trim. For older Redlands homes, this is where our pre-demo inspection earns its keep. We open the shower wall and check the drain line before final pricing, so the number we quote is the number you pay barring conditions we can’t see from any side.

Shower and Tub Replacement
Replacing a tub with a walk-in shower is the most common request we get in Redlands, especially from homeowners in 1960s and 70s tract homes where the original tub is chipped, short, or surrounded by tile that’s failed. We do full replacements, not liners. That means the old tub comes out, the subfloor gets checked for rot, the drain gets replaced if it’s cast iron or corroded, and the new pan and waterproofing go in to code. In pre-war homes near the historic core, we match fixture and tile styles to the era where it matters and upgrade the plumbing where it’s needed.

ADA-Compliant Bathroom Modifications
For Redlands homeowners planning to age in place or accommodate a family member with mobility needs, we handle ADA-compliant remodels: curbless showers with linear drains, reinforced walls for grab bars, wider door openings, and comfort-height toilets. This work is especially relevant in Redlands’ older housing stock, where narrow doorways and 5-foot tubs are standard. We’ve converted cramped hall baths in 1920s bungalows into open, accessible spaces without moving walls, and we can tell you honestly whether a curbless shower is feasible on your existing floor joists before you commit to the design.

Trusted Brands We Service in Redlands
On Redlands bathroom remodels we work with materials and brands that hold up to inland heat and hard water: James Hardie substrates in wet-zone walls where we’re doing exterior-adjacent bath additions, and quality plumbing fixtures and shower systems we’ve tested across hundreds of projects. For homeowners also planning an ADU on the same property, we can coordinate the bath remodel with a Plant Prefab, Boxabl, or Tuff Shed ADU build so both projects share one permit timeline and one contractor. The point: we’re not tied to one brand or one method. We recommend what fits your house and your budget, and we’ll explain why in plain English.
Common Bathroom Remodeling Problems We See in Redlands Homes
- Knob-and-tube wiring behind bathroom walls. Homes built before about 1940 in Redlands’ historic core frequently still have active knob-and-tube circuits serving bath lighting and outlets. Once the wall is open, current code requires replacement, and that’s a real cost we plan for before demo, not after.
- Cast-iron drains with root intrusion or corrosion. Redlands’ older homes have cast-iron drain lines that have spent 70 to 100 years in soil. We regularly find roots in tub drain lines near mature landscaping, and that’s a plumbing repair we can scope and price during our pre-demo inspection.
- Water-damaged framing under tubs and showers. Failed showers leak for years before anyone sees the damage. In Redlands’ pre-war homes especially, we find rotted subfloor and studs once the tile comes off, which means structural repair before any tile goes back.
- Failed waterproofing in tiled showers. Older Redlands showers were often built with drywall or green board behind tile, not the modern membrane systems we install now. By the time grout cracks and tiles loosen, the wall cavity is usually wet. We replace the whole assembly, not just the surface.
Pricing for Bathroom Remodeling in Redlands, CA
A hall bath remodel in Redlands runs $18,000 – $28,000. A primary bath with custom tile, a curbless shower, and a freestanding tub runs $35,000 – $55,000. ADA conversions typically land between $22,000 and $40,000 depending on whether we’re moving walls and how much framing and plumbing changes. Here’s what moves the number in this market:
- Demo and disposal: $1,800 – $3,500, higher on second-story baths in older homes where access is tight
- Full shower replacement with waterproofing and tile: $8,000 – $14,000
- Electrical upgrades (including knob-and-tube replacement when found): $2,500 – $7,000
- Cast-iron drain replacement: $2,000 – $5,000 depending on access and length
- Framing and subfloor repair: $1,500 – $4,500, higher when rot extends to structural members
We write allowances into every Redlands contract for exactly the discoveries this housing stock produces. If we open a wall and find something we couldn’t have known about, you receive a written change order with the cost before we do any extra work. You approve it, or you don’t, and we adjust. Call (833) 589-8273 for a free estimate, and we’ll give you a line-item price based on your specific house, not a range based on a Google search.

FAQs – Bathroom Remodeling in Redlands
Opening walls in pre-war Redlands homes frequently reveals knob-and-tube wiring, cast-iron drains near the end of their service life, and framing damaged by decades of slow leaks. Current code requires replacing knob-and-tube circuits once the wall cavity is open, and a 1925 cast-iron drain that’s been in Redlands soil for 100 years often fails the moment we disconnect the old tub. These aren’t upgrades we choose to sell you; they’re corrections the building code mandates once conditions are exposed. We plan for them with written allowances in your contract, so the “extra” is a line item you already knew about, not a surprise invoice.
Call (833) 589-8273 and we’ll walk your specific house and tell you what we’d expect to find before any walls come down.
We inspect first, then price, then demo. Before we finalize a contract, we open the wet wall from the shower side and the ceiling below the tub if there’s access. We look at the wiring, the drain, and the framing. If we find active knob-and-tube, we write the rewire into the contract before you sign. If we find something after demo that no inspection could have caught, we issue a written change order with the exact cost, and we don’t proceed until you approve it. We recently remodeled a hall bath in a 1925 Craftsman near the University of Redlands. Once we opened the walls, we found cloth-wrapped wiring spliced into a modern circuit and a cast-iron drain with root intrusion. We priced the electrical rewire and drain replacement in writing before proceeding, and the homeowner approved the supplement the same day. That’s the process on every job.

Yes, in the historic core around downtown Redlands (92373), exterior-visible changes like moving a window, adding an exhaust fan penetration, or altering a roofline can trigger the city’s historic preservation review. Interior-only remodels generally don’t, provided you’re not changing the street-facing elevation. But an interior remodel that adds a bathroom window where one didn’t exist, or that requires a new exterior vent, can get pulled into design review. We know the triggers and we’ll tell you before you pay for drawings whether your plan will need sign-off. In the 92374 tract-home neighborhoods, this rarely comes up.
Call (833) 589-8273 if you’re in the historic district and want to know whether your plan will need review.
The most common failure is tile over drywall or green board, which was standard practice in Redlands homes built before about 1990. Once grout cracks or caulk fails, water moves through the wall cavity and rots the framing behind. The second is shower pans built without a proper preslope, which causes water to pool and eventually seep into the subfloor. We also see curb construction where a wood curb was never properly wrapped with a waterproof membrane. By the time the tiles loosen, the damage behind the wall is usually extensive. We replace the entire assembly with a modern waterproofing system: backer board, membrane, and proper drainage. The tile is just the visible layer.
If you suspect a failed shower in your Redlands home, call (833) 589-8273. We’ll assess the damage and give you a straight answer on repair versus replacement.
Redlands summers regularly hit 100°F and higher, with dry Santa Ana conditions that affect how we sequence work and how we build. We schedule demo and rough-in work early in the day during heat weeks, and we size bathroom exhaust to move the humid air that inland heat makes heavier. The bigger issue is material selection: cheap adhesives and caulks fail faster in the high heat we get in the Inland Empire, so we spec products rated for the climate, not coastal assumptions. On bathroom additions where an exterior wall is involved, the same heat load means insulation and moisture barriers get sized for Redlands summer peaks, not a mild climate. It’s a small thing until it isn’t. Then it’s a wet wall and mold behind the tile.
