Fast, Reliable Bathroom Remodeling Across Lake Arrowhead
Bathroom remodeling in Lake Arrowhead typically runs $18,000 – $45,000 for a full gut-and-rebuild, with smaller refreshes starting around $9,000. Most jobs take three to six weeks once demolition starts, though mountain permitting and materials delivery can add a week or two. If you’re planning a hall bath update in a 1970s cabin off State Highway 173 or a primary suite addition near the lake, call us at (866) 730-4828 for a free estimate or learn more about our Cover service in Lake Arrowhead. We’re Bungalow ADU Builders, led by Nate Calloway, and we’ve spent enough time in 92352 to know what’s behind these walls before we open them.
What makes Lake Arrowhead different from a bathroom remodel down the hill in San Bernardino or Riverside isn’t just the drive. It’s what the original builders did with the materials they had in the 1960s through the 1990s, and what four decades of freeze-thaw cycles, pine needle moisture, and hillside settling does to a framed bathroom. We plan for that before we demo. It changes the quote, the schedule, and the way we waterproof.
Why Bungalow ADU Builders Is Lake Arrowhead’s Preferred Bathroom Remodeling Team
We’re not a franchise operation that sends a rotating crew up the mountain. Bungalow ADU Builders handles Bathroom Remodeling as a core service line, not a side job between kitchen gigs. Nate Calloway built this company around ADUs and the interior trades that make a unit actually livable: kitchens and baths included. That focus matters when your 1972 hall bath turns up knob-and-tube wiring and a rotted subfloor the same week your permit inspection is scheduled.
Our Lake Arrowhead customers tend to ask the same three questions before we start: what do you do when you find something the last contractor left buried, how do you price it, and will the county inspector care. We answer all three the same way: inspection first, allowance money written into the contract, and every surprise priced and approved in writing before we touch it. No mid-project phone call asking for five thousand dollars with no paperwork.
We’ve done remodels in Arrowhead Villas, near the Country Club, and off Peninsula Drive. We know which roads Caltrans plows first and which deliveries need a day of buffer in January. That local knowledge shows up in the schedule and the price, not in a marketing brochure.
Our Bathroom Remodeling Services in Lake Arrowhead
Most of what we do in Lake Arrowhead falls into four buckets. Each one starts with an inspection of what’s currently behind the surround, under the floor, and in the wall cavity. That’s not optional up here. The mountain doesn’t care how nice the new tile looks if the framing under it is already compromised.
Full Bathroom Gut and Rebuild
A full gut in 92352 means pulling everything to the studs, and that’s usually where the real project begins. In a 1960s-1990s Lake Arrowhead cabin, we regularly find framing that was never sized for a tile and mortar bed: 2×6 joists notched too deep for drain lines, or tub bays that sag after forty winters. We fix the structure first, then build the new bathroom correctly from the floor up. You get a written scope that includes subfloor replacement, new supply and drain lines, and a modern waterproofing system before any finish work starts.
Shower and Tub Replacement
Lake Arrowhead’s older bathrooms almost always have failed lead pans or mastic-and-tile showers that have been quietly seeping into the subfloor for years. You don’t see it until the old surround comes out. When we replace a tub or shower in Lake Arrowhead, we assumed that’s what we’ll find and the contract reflects it. The new assembly gets a properly sloped pan, cement board or a sheet membrane system, and a flood test before tile goes up. That’s standard practice for us, not an upgrade.
Bathroom Addition for ADUs
Bungalow ADU Builders is built around the full accessory dwelling unit lifecycle, including the bathroom that makes a unit rentable. When you’re adding a bathroom to a detached ADU on a steep Lake Arrowhead lot, the plumbing is part of the same scope as the foundation and the shell. We handle the rough-in, the finish work, and the coordination with the same project manager. No handoff to a separate trade contractor who’s never seen the site.
Water Damage Repair and Mold Remediation
Mountain humidity and freeze-thaw cycles are tough on bathrooms. A vent fan that was never ducted properly, or a window that’s been leaking for a decade, creates mold behind the wallboard that you won’t see until we open it. We don’t do mold abatement as a separate company. We identify the moisture source, fix it so it doesn’t come back, and rebuild the bathroom. If remediation is required beyond what a licensed remodeler should handle, we’ll tell you that plainly and help you get the right specialist involved.

Trusted Brands We Service in Lake Arrowhead
We’re brand-agnostic by design. That means we’re not funneling your Lake Arrowhead bathroom toward one manufacturer’s system because we have inventory to move. For bathroom remodels and ADU interiors, we work with the same product lines we use on our larger builds: Bathroom Remodeling in Lake Arrowhead projects regularly include James Hardie backer board for wet areas, and when a client’s ADU shell comes from Plant Prefab or Abodu, the bathroom finishes come from our team. We keep common materials stocked locally for Arrowhead jobs so a missing trim piece doesn’t stall your project for a week waiting on a freight delivery.
Common Bathroom Remodeling Problems We See in Lake Arrowhead Homes
The housing stock in Lake Arrowhead is mostly 1960s-1990s mountain cabins and second homes. Wood-sided, pier-and-post or stepped foundations on slopes, many on septic rather than sewer. Here’s what that means when you open a bathroom wall:
- Knob-and-tube or early NM wiring: A lot of these cabins were wired before GFCI protection was code, and some still have original two-wire circuits. Once the walls are open and a permit is pulled, the inspector will require dedicated, grounded, GFCI-protected circuits for the bathroom. We price that into the initial scope so it’s not a surprise.
- Undersized and notched framing: Joists cut for drain lines, tub bays framed with 2x6s that were fine for a fiberglass surround but can’t carry a tile assembly. Up here, that’s the rule, not the exception. We sister or replace as needed before any tile is set.
- Failed waterproofing: Lead pans that cracked decades ago, mastic that lets go in freeze-thaw cycles, no vapor barrier behind old tile. The subfloor underneath is often rotten. We inspect, we price the fix, we show you photos before we rebuild.
- Cast-iron drain failures: The cast-iron closet bends and drain lines in these older cabins crack over time, especially where they pass through unheated crawl spaces. We replace with ABS or PVC and bring everything to current code.
Pricing for Bathroom Remodeling in Lake Arrowhead, CA
Here’s what we see in the Lake Arrowhead market, based on the actual condition of the homes we work on:
- Cosmetic refresh (new vanity, fixtures, paint, mirror, lighting): $9,000 – $15,000
- Tub or shower replacement with new surround and waterproofing: $12,000 – $22,000

The range depends on what’s behind the walls, which is exactly why we do a walk-through and a scope review before we quote. A 1970s hall bath in Lake Arrowhead with original wiring and a rotten subfloor is going to land higher than a 1995 second-home bath that’s been maintained. What we don’t do is quote low to win the job and then change the price mid-project. Allowances for known-risk items get written into the contract. Anything we find that wasn’t anticipated gets priced and approved in writing before we order a single material. Call (866) 730-4828 to schedule your free estimate.

FAQs – Bathroom Remodeling in Lake Arrowhead
A Lake Arrowhead remodel differs in three ways. First, the age and construction of the housing stock: 1960s-1990s mountain cabins with wood framing, pier-and-post foundations, and wiring that predates GFCI. Second, the climate: at 5,000 – 6,000 feet, freeze-thaw cycles stress plumbing and waterproofing in ways a flatland San Bernardino bathroom never sees. Third, the permitting and inspection environment: San Bernardino County requirements plus Lake Arrowhead Community Services District rules and, on many lots, a homeowners association review. We plan for all three before we start demo.
The most common are knob-and-tube or ungrounded wiring, joists notched too deep for drain lines, failed lead pans or mastic showers that have rotted the subfloor, and cracked cast-iron drains. We recently opened a hall bath in a 1972 wood-sided cabin off Peninsula Drive and found the subfloor had been sistered with scrap plywood and the cast-iron drain was cracked at the closet bend. After our inspection, we priced a new subfloor, ABS re-pipe, and a full waterproofing system, then had the homeowner approve the change order in writing before we ordered materials. The finished bath now has a properly sloped pan and a dedicated GFCI circuit the original cabin never had.
We write allowance money into the contract for the known risks on older Lake Arrowhead homes: subfloor replacement, drain line repair, and wiring upgrades. If we find something beyond the allowance, we stop, document it with photos, explain the issue, and get your written approval on a change order before we order materials or continue work. No surprises on the final invoice.
Yes, and this is one area where mountain experience matters. Bathroom supply lines and drains in Lake Arrowhead need to be protected against freeze-thaw cycles, especially in crawl spaces and exterior walls. We use freeze-protected plumbing details, proper vapor barriers, and waterproofing systems rated for the temperature swings we get at 5,000 feet. A bathroom built to flatland San Bernardino standards will fail up here. We don’t build to flatland standards.
Often, yes. Once the walls are open and the work is permitted, the county inspector will require the bathroom’s electrical to meet current code: GFCI protection, a dedicated 20-amp circuit where needed, and grounded wiring. If your cabin still has original knob-and-tube or early NM cable, that’s a mandatory upgrade. We include that in the initial scope so the permit inspection doesn’t become a renegotiation. Call (866) 730-4828 for a free estimate and we’ll walk you through what applies to your specific home.
