If you’re planning a bathroom remodel in Crestline, call (877) 658-7475 for a free estimate that accounts for the reality of your home, not a generic square-footage guess.
Why Casita ADU Builders Is Crestline’s Bathroom Remodeling Company
We’re ADU and remodel specialists, not a general contractor picking up bathroom work on the side. That focus matters in Crestline, where mid-century cabins often need structural and electrical corrections before new finishes can go in, which is why homeowners trust Dvele in Crestline for precision-built solutions. Nolan Treffert leads our team, and our approach is built around one contract and one crew from first inspection through final grout.
Our in-house bathroom remodeling capability grew out of finishing ADU interiors to the same standard homeowners expect in their primary baths. That means we’re used to tight spaces, steep site access, and older framing. Crestline homeowners call us because we don’t flinch when a shower valve relocation turns up spliced cloth wiring or a rotted subfloor under a 1970s lead pan. We stop, document, price the correction in writing, and get approval before touching anything beyond the original scope. That’s how a remodel quote stays honest while the house tells us what it needs.
Serving Crestline means accounting for snow-load, freeze protection, and fire-resistance requirements that flatland remodels never face. We’ve worked on cabins off Zurich Drive, around Lake Gregory, and up toward Top Town where driveway grades and tree clearance drive design decisions. One contract, one team, no handoffs.
Our Bathroom Remodeling Services in Crestline
Full Bathroom Gut and Rebuild
A full gut in Crestline is rarely cosmetic. Most of these cabins were built between 1950 and 1980 with 2×4 framing, minimal insulation, and no vapor barrier. When we open a wall, we routinely find kraft-faced insulation installed paper-side-out against exterior sheathing, which is a code violation under San Bernardino County’s cold-weather assembly requirements and a moisture trap in freeze-thaw cycles. We correct the cavity, re-insulate to current code, and rebuild with a properly vented or unvented assembly suited to 4,500 feet of elevation. A typical full bathroom gut and rebuild in Crestline runs $22,000 – $38,000 depending on fixture level and what the framing reveals.
Waterproofing and Tile Substrate Correction
1970s cabin bathrooms often have tile set over greenboard with surface waterproofing, or lead pan liners that cracked decades ago. Once the tile comes off, the substrate is usually done. We replace wet or crumbling board with cement backer or a foam board system, install a bonded waterproofing membrane, and rebuild the pan with a proper pre-slope and drain assembly. If your joist bays are too shallow for the drain slope, which happens often on pier-and-beam floors in Crestline, we frame a small curb or modify the joists with engineering signoff. Waterproofing and substrate correction alone typically runs $6,000 – $14,000 before finish tile.
Electrical and Plumbing Code Upgrades
Older Crestline bathrooms frequently fail electrical inspection on ungrounded circuits, missing GFCI protection, or undersized panels. A permit-triggered remodel means the bathroom circuit must meet current code, and that often requires a new home run from the panel or a subpanel upgrade if your mountain cabin is still on a 60-amp service. Plumbing runs hold their own surprises: galvanized supply lines that are corroded inside, drain lines with bellies from foundation settlement, and venting that was never correct. Electrical rough-in for a bathroom remodel in Crestline typically adds $3,500 – $9,000 once hidden conditions are priced. We write these as allowances in our contract so you know the range before we start.
Shower and Tub Replacement with Freeze-Protected Plumbing
Crestline winters freeze pipes that flatland homes never worry about. When we install a shower valve or tub filler, we keep supply lines off exterior walls where possible, use freeze-rated fixtures when asked, and insulate any runs that must live in a cold bay. Shower and tub replacement, including demo, valve relocation, waterproofing, and tile, runs $9,000 – $18,000 in Crestline depending on what the wall cavity gives us.
Every one of these services falls under our broader Bathroom Remodeling umbrella: one crew that understands mountain construction from the studs out.

Trusted Brands We Service in Crestline
We work with materials that hold up at altitude and against wildfire exposure. For bathroom builds inside our ADU and remodel projects, we use James Hardie fiber-cement in exterior applications, and inside the bath we specify substrates and waterproofing from brands engineered for wet, cold, and fire-prone environments. We’re a Tuff Shed partner for ADU conversions, which means a shed-to-ADU project often includes a full bathroom build out, and our ties to Abodu and Cover keep us current on compact bath layouts that maximize every inch of a smaller footprint. For Crestline customers, we stage materials before we start so narrow roads and steep driveways don’t become mid-project delays.
Common Bathroom Remodeling Problems We See in Crestline Homes
- Cloth-wrapped or ungrounded wiring behind the walls. A 1962 cabin off Zurich Drive taught us exactly how bad this can get: our crew relocated a shower valve and found spliced cloth wiring without a junction box, plus framing notched past code for an old medicine cabinet. We stopped work, wrote a supplemental scope with engineered repairs and a dedicated GFCI circuit, and had written approval before touching the framing.
- Failed lead pans and surface waterproofing over greenboard. Once tile is off, these 1970s-era assemblies are almost always past saving. We replace the substrate fully rather than patching over rot.
- Shallow joist bays on pier-and-beam floors. A properly sloped shower drain needs depth. Many Crestline cabins don’t have it, which means a curb or a framing modification. We flag this during the estimate, not after demo.
- No vapor barrier and incorrect insulation orientation. Kraft paper against cold exterior sheathing is a mold and condensation problem at 4,500 feet. Full cavity correction is standard on our gut-and-rebuild projects.

FAQs – Bathroom Remodeling in Crestline
Yes, a permit is required for any Crestline bathroom remodel that moves plumbing, alters framing, or changes the electrical system. The moment walls are open, San Bernardino County requires the exposed work to meet current code, which is what triggers upgrades to wiring, insulation, waterproofing, and sometimes the panel. Call (877) 658-7475 and we’ll walk you through what your specific project will trigger before you commit.
Expect an electrical correction. Cloth-wrapped wiring is typically ungrounded and cannot support a GFCI circuit, which every bathroom requires. We’ll add a new home run from the panel, install a dedicated GFCI outlet, and bring any other exposed circuits in the remodel area up to code. We price this as an allowance so the cost range is on paper before demo starts.
Freeze protection changes where we place plumbing. Supply lines stay off exterior walls whenever layout allows, and any line that must live in an exterior cavity gets insulation and, where practical, heat tape or freeze-rated fixtures. Snow load also affects vent terminations and any roof penetrations from new exhaust fans, which we flash and seal to San Bernardino County cold-weather standards.
Sometimes, but don’t count on it. If the bathroom circuit is grounded, has a GFCI, and the panel has capacity, a cosmetic remodel may not trigger broader electrical work. If we find ungrounded cloth wiring or a 60-amp panel, the permit will require corrections. We inspect before we quote so you know which path you’re on. Call (877) 658-7475 for a free assessment.
Kraft-faced insulation installed paper-side against exterior sheathing, which violates cold-weather assembly code and traps moisture. Combined with no vapor barrier and 2×4 cavities, it’s the single biggest reason a Crestline bathroom remodel quote moves once the wall is open. We correct the cavity fully and price it in writing before we touch the framing.
