Bathrooms are small rooms with a lot packed into them, and their cost per square foot is among the highest of any room in the house. This guide uses the published Cost vs. Value figures as a reference point, explains what those projects include, and covers what changes the number for a Ventura County bathroom.
These are national averages, not LE Construction prices. Your price comes from a written estimate after we have looked at the room, the floor and the plumbing.
The published numbers
The 2025 Cost vs. Value report priced several bathroom projects:
- Midrange bath remodel: $26,138. An existing 5-by-7-foot bathroom gets a new tub, ceramic tile surround, toilet, vanity with a solid-surface top, lighting, mirror and ceramic floor, with fixtures staying in place.
- Upscale bath remodel: $81,612. A larger bathroom is reworked with relocated fixtures, a tiled shower with frameless glass, a freestanding tub, a stone double vanity and higher-end finishes.
- Universal design bath: $42,183. An existing bathroom is made accessible, with a curbless shower, a wider doorway, grab bars, a comfort-height toilet and similar features.
- Bathroom addition, midrange: $60,645. A new bathroom is built as an addition, with its own foundation, framing and plumbing.
The gap between midrange and upscale is mostly about size, moving fixtures and finish level. In real Ventura County remodels, the other big variable is what is hiding behind the old tile.
What pushes the cost up here
Hidden water damage
Older showers were often built with tile and grout alone, or with a membrane that failed long ago. When they come out, the framing behind them can be wet or rotted. A wax ring that failed years ago can soften the subfloor around the toilet. We check for both at the first visit, and in raised-floor houses we look from the crawlspace.
Moving fixtures on a slab
Many homes in Oxnard, Camarillo, Simi Valley and the Conejo Valley sit on concrete slabs. Moving a toilet or shower drain means cutting the slab, rerouting the drain and patching it. Keeping fixtures where they are saves a lot.
Code items on a permitted remodel
A permitted bathroom remodel includes an exhaust fan vented outside with humidity control, as California code requires, and in homes built before 1994, replacement of noncompliant fixtures with water-conserving ones before final approval. New fixtures already meet that rule, but old ones cannot be reused.
Coastal moisture and hard water
Near the beach, bathrooms stay damp, so a properly sized fan matters even more. Hard water across much of the county leaves scale on glass and valves; easy-clean glass coatings and a softener are worth budgeting for.
Where the money goes
In most bathroom remodels, the largest pieces are:
- Demolition and repair of whatever is behind the walls and under the floor.
- Plumbing, including the valve, drains and supply lines.
- Waterproofing and tile, where labor is the main cost.
- Vanity, counter and fixtures, which range widely in price.
- Glass, which is measured after tile and often overlooked in budgets.
Ways to spend wisely
- Keep the toilet and drains where they are.
- Use a large-format porcelain tile on the walls and save the decorative tile for a niche or accent.
- Choose a fixed glass panel instead of a door where the layout allows.
- Add grab-bar blocking now, even if bars come later.
We price bathrooms line by line, with any conditions we find at the visit included. See our bathroom remodeling page, shower remodels and tub conversions and accessible bathrooms for more on the work itself.

Frequently asked questions
What does a midrange bathroom remodel include in published surveys?
The Cost vs. Value midrange project updates an existing small bathroom, roughly 5 by 7 feet, replacing the tub, tile surround, toilet, vanity and counter, faucets, lighting and floor tile without moving anything. It does not include moving walls or plumbing, which is why real remodels often cost more.
How much more does an accessible bathroom cost?
The 2025 Cost vs. Value universal design bath, which adds a curbless shower, wider door, grab bars and other accessible features, came in about $16,000 above the midrange remodel nationally. Building blocking for grab bars during any remodel costs very little, even if you add the bars later.
Why do bathroom remodels in older homes go over budget?
Mostly because of water damage nobody could see: a soft subfloor around the toilet, rotted framing behind an old shower, or a fan that has been venting into the attic. We probe the floor and check from the crawlspace where we can, and price what we find before you sign.
Is it cheaper to keep the tub than to build a walk-in shower?
Replacing a tub with another tub is usually cheaper than building a tile shower, because a shower needs a waterproofed pan, more tile and glass. A tub-to-shower conversion is still one of the most popular upgrades because the result is safer and easier to use.
