Planning a tub-to-shower conversion in Sacramento
If you rarely use your bathtub, a walk-in shower may suit your daily routine better. A tub-to-shower conversion in Sacramento can give you more room and an easier entry. Often, the new shower fits where the old tub stood.
The work involves more than replacing one fixture, though. The drain, shower valve, floor and waterproofing all affect the plan. Your home’s age and foundation can also change the scope.
This guide covers the design choices, building rules, costs and steps to expect. It also explains what to check before work starts.
Key takeaways
- A conversion makes sense when the tub sees little use or is hard to step over.
- Drain placement, valve changes and waterproofing shape much of the work.
- Raised foundations and concrete slabs can call for different plumbing methods.
- Shower size, ventilation, safety glass and permits depend on local rules and project scope.
- Drain changes, damage found behind the old tub, and your tile and glass choices drive the cost and schedule.
When does a tub-to-shower conversion make sense?
A conversion is worth considering if everyone in your home showers rather than bathes. The old tub may take up space without serving your needs. A walk-in shower can make that part of the bathroom easier to use.
It may also help if stepping over a tall tub wall feels unsafe. A low curb reduces the step, while a curbless entry removes it. Both choices can make daily bathing more comfortable.
Think twice before removing your home’s only tub. Young children may need one, and some future buyers may prefer one. Your family’s plans matter more than any single design trend.
What does a tub-to-shower conversion involve?
Most projects follow a similar order. The exact work depends on the old tub, plumbing and new shower design.
- Remove the bathtub and the surrounding wall finishes.
- Check the framing, floor and pipes for damage.
- Move or adapt the drain if the shower layout requires it.
- Update the shower valve and water connections as needed.
- Install approved wall backing and a full waterproofing system.
- Set a shower pan (the sloped base that carries water to the drain) or build a sloped tile shower floor.
- Finish the walls with tile or approved shower panels.
- Fit the shower opening, fixtures, trim and any glass.
Some conversions stay within the old tub opening. Others need floor, wall or pipe changes. For example, a curbless shower may need more work below the finished floor.
Waterproofing is one of the most important steps. Tile and grout alone do not stop water from reaching the wall. A sound system protects the framing and floor below the shower.
How Sacramento homes affect the work
Sacramento homes vary in age, layout and foundation type. Two similar bathrooms may need very different plumbing work.
Older homes in East Sacramento, Land Park, Curtis Park and Midtown may have crawl spaces. Where there is access below the floor, plumbers can often reach the drain without cutting concrete. Some homes also have older cast iron drains or galvanized pipes worth checking.
Many mid-century homes in Arden-Arcade, Carmichael and South Land Park have 60-inch tub alcoves, the three-walled nook the tub sits in. These openings can often fit a shower without moving the nearby walls. The actual dimensions still need to be checked.
Many newer homes in Natomas, Elk Grove, Folsom and Rancho Cordova sit on concrete slabs. Moving a drain in these homes may mean cutting the slab and repairing it afterward. The foundation must be checked before anyone sets the scope.
Drain placement and plumbing changes
A bathtub drain usually sits near one end. Your new shower may need a different drain position. That depends on the shower pan and the way the floor slopes.
Some ready-made shower pans fit common tub drain locations. Others use a center drain or a linear drain. A linear drain is a long, narrow drain that runs along one wall.
Either way, the new design may call for changes below the floor. The pipe size, slope and trap (the curved pipe that blocks sewer gas) must also work with the new shower. A plumber should check these parts before the drain location is final.
We’ve handled this kind of work in Elk Grove. Our Elk Grove secondary bathroom remodel included cutting the slab and changing the drain lines. The team then replaced the old tub with a shower.
Updating the shower valve
The shower valve controls water flow and temperature. An old tub valve may not meet current rules or work with new fixtures. That is why conversions often include a valve update.
The City of Sacramento calls for pressure-balanced or thermostatic mixing valves in shower installations. These valves help limit sudden changes in water temperature. The rule applies when the surround comes out or the valve is replaced.
Since most conversions remove the old surround, check valve needs early. That helps prevent changes after the walls are closed.
Choosing a curbed or curbless shower
Both designs can work well. The right choice depends on how you use the shower and what lies below the floor.
Curbed showers: A low raised edge helps keep water inside the shower. It can also limit the amount of floor work needed. This is often a good fit when you want a simpler conversion.
Curbless showers: The bathroom floor meets the shower entry without a raised step. This makes entry easier and gives the room a more open look. The shower still needs enough slope to move water toward the drain.
A curbless design may require changes to the floor framing or slab. It also needs careful planning to keep water from leaving the shower. So the opening and floor design should be planned together.
A low entry can help with aging in place. Still, it does not make a bathroom fully accessible on its own. Clear floor space, slip-resistant surfaces, controls, seating and grab bars also matter.
Shower size requirements in Sacramento
The City of Sacramento’s bathroom remodel handout lists minimum shower dimensions. In general, a finished shower needs at least 1,024 square inches of floor area. It must also fit a circle 30 inches across.
The handout calls for a hinged shower door at least 22 inches wide that swings outward. Other entry designs should be checked with the building department. This helps avoid a layout that fails inspection.
There is an exception for some tub replacements. When a tub becomes a shower base at least 30 inches wide and 60 inches long, the usual minimum size rules do not apply. That may help when you want to keep the original alcove.
These rules come from the City of Sacramento’s Residential Bathroom Remodel Handout (CDD-0418), revised January 1, 2026. Other cities and Sacramento County may have different review steps. Always confirm the rules for your address.
Shower walls and waterproofing
A shower sends water onto its walls every day. The finish needs to shed that water, while the system behind it protects the home.
The city’s handout calls for a smooth, nonabsorbent surface at least six feet above the floor. It also limits the materials used behind the finish. Standard moisture-resistant greenboard is not an approved shower backing material.
Tile alone is not waterproof. Water can pass through grout and reach the layers below. The waterproofing system, seams and drain connection all need proper installation.
For a wider look at these decisions, see our bathroom remodeling service. It covers planning, plumbing, shower work and other upgrades that may be part of your project.
Shower glass and safety requirements
Shower doors and fixed glass panels need approved safety glass. This helps reduce the risk of serious cuts if glass breaks.
Windows near a shower may also need safety glass. The rule depends on the height of the glass and its distance from wet areas. Check existing windows before changing the shower layout.
Framed, semi-frameless and frameless glass are common choices. A fixed panel can also suit some shower designs. The opening should be wide enough for easy use and planned to keep water inside.
Bathroom ventilation and lighting
A daily shower adds moisture to the room. Without good ventilation, damp air can damage paint, trim and drywall. It can also support mildew growth.
The City of Sacramento handout calls for a bathroom exhaust fan with humidity control. It lists 50 cubic feet per minute for a fan used at intervals. For continuous use, it lists 20 cubic feet per minute.
Lighting matters too. Fixtures above the shower need a damp-location rating. If they face direct water spray, they need a wet-location rating.
Hanging fixtures, track lights and ceiling fans also face limits near showers and tubs. Check these rules if you plan to move lights or change the shower area.
Do you need a permit for a tub-to-shower conversion in Sacramento?
Most tub-to-shower conversions involve plumbing work that needs a permit. The permit path depends on what you change and where you live.
The City of Sacramento offers a Minor Bathroom Remodel Permit for certain like-for-like replacements. These projects may not need full construction plans, but an inspector still checks the work on site. Replacing a tub with a shower is not always a like-for-like change.
Moving a drain, changing the floor or altering the room may require more review. The city’s handout also calls for full plan review when work creates or moves doors or windows in the bathroom’s outer walls.
Your address decides which agency handles the permit. For example, Elk Grove, Folsom, Rancho Cordova and Roseville have their own building departments. Many homes in Arden-Arcade, Carmichael and Fair Oaks fall under Sacramento County.
Before work starts, confirm the current rules for your property. Our guide to bathroom remodel permits in Sacramento explains the steps in more detail.
What affects the cost of a tub-to-shower conversion?
Two bathrooms of the same size can have very different costs. Plumbing, floor work and material choices account for much of the difference.
- Drain changes: Moving the drain adds plumbing work and may require slab repairs.
- Shower entry: A curbless design may need changes below the finished floor.
- Wall and floor materials: Custom tile takes more work than many ready-made shower systems.
- Glass: Large panels and frameless doors affect material and installation costs.
- Fixtures: Extra spray heads, handheld showers and built-in niches add to the scope.
- Hidden damage: Leaks, worn pipes or soft framing may need repair.
- Permits: Fees and inspection steps depend on the local agency and the work.
A ready-made pan and wall panels often need less custom work. A tiled, curbless shower with a moved drain usually needs more. The condition of the room can change either plan.
Some problems only show up after demolition. Leave room in your budget for repairs that cannot be seen at the first visit.
How can you estimate the cost before you start?
First, decide what you want the new shower to do. Do you need a lower entry, more room or easier cleaning? Then look at the drain, floor and wall conditions.
Our bathroom remodel cost calculator can help you explore your budget. It is a planning tool, not a quote for your home. A written estimate can account for the plumbing, materials and work your bathroom needs.
How long does a tub-to-shower conversion take?
The schedule depends on the existing bathroom and your new shower design. A ready-made shower system often takes less installation time than custom tile.
Demolition and plumbing come first. Then the crew handles waterproofing, finishes and any inspections. Each step needs to happen in the right order.
Custom glass may take longer because it is measured after the tile work is done. Water damage or old pipes can also add repair time. Material delivery and permit timing may affect the schedule.

Should you replace the tub or remodel the whole bathroom?
A focused conversion may be enough if the rest of the bathroom works well. You can update the shower without replacing a good vanity, toilet or floor. Our Bath Refresh offer includes tub-to-shower conversions for this kind of project.
A full remodel may make more sense if you also want new lighting, storage or a better layout. For example, a curbless shower and new floor are easier to plan together. This can also reduce the need to reopen finished walls later.
Our bathroom remodeling team can help you compare a focused shower update with a larger project. We look at your daily needs and explain what each option involves.
Paying for a tub-to-shower conversion
Some homeowners use savings, while others consider financing. Financing options are available through Acorn Finance, a third-party lending marketplace.
Lenders decide approval, rates and loan terms. Review the full cost before you accept an offer.
Common questions about tub-to-shower conversions
Can you convert a bathtub into a shower without moving the drain?
Sometimes. Some shower pans fit the drain location used by a standard tub. That may reduce the plumbing work needed.
The pipe size, trap and slope still need to meet the new shower’s needs. A plumber should check these parts before you choose the pan.
Should you keep at least one bathtub in your home?
Keeping one tub may help if you have young children or enjoy taking baths. Some homebuyers also like having that choice.
Still, there is no single answer for every household. Think about your family’s needs now and how you plan to use the home in the future.
Can a tub-to-shower conversion make a bathroom easier to use?
Yes. A low curb or curbless entry can reduce the need to step over a high tub wall.
For better access, also consider slip-resistant flooring, grab bars and room to move. The location of the controls and space for a seat can make a difference too.
Can you use a shower curtain instead of glass doors?
Sometimes. A curtain can work with certain shower layouts and may be easier to clean or replace. The opening must still help keep water inside.
The City of Sacramento’s handout includes rules for hinged shower doors. Have your contractor confirm the entry design with the building department before making a final choice.
Will your bathroom be usable during the conversion?
The tub or shower will be out of service during construction. The sink and toilet may stay usable during some stages, depending on the plumbing work.
If this is your only bathroom, we’ll talk through water shutoffs and temporary plans before work begins. That will help your household prepare.
