What Sets Our ADU Bathroom Remodeling Apart in Antelope, CA
ADU bathrooms are not the same as bathrooms in a main house. They have tighter footprints, shared plumbing walls, and Sacramento County code requirements that differ from city limits. We know those differences. Our team handles everything from the permit submission to the final inspection. We do not subcontract tile to one crew and plumbing to another. One team manages your project start to finish. That means fewer delays, better coordination, and a result that holds up for years. For a full overview of our ADU services, see our ADU Remodeling page. We also offer ADU Kitchen Remodeling for units that need both rooms updated.
ADU Bathroom Remodeling Services in Antelope, CA
We work on ADU bathrooms of all sizes and conditions across Antelope and Sacramento County. Some need a full gut renovation. Others need a tile refresh or a new vanity. Some need grab bars and a curbless shower for a family member who uses a walker. We scope the work correctly, pull the right permits, and build it to last. Below are the specific services we provide.
Full ADU Bathroom Gut Renovation
Sometimes a repair is not enough. When tiles are cracked and the substrate behind them is wet, or when the plumbing is so outdated the whole system needs replacing, a full gut renovation is the right call. We remove everything down to the studs and subfloor. We fix what is damaged before anything goes back in. Then we install waterproofing, new tile, new fixtures, and proper ventilation. Every full gut renovation goes through Sacramento County permits and inspections. You get a bathroom that is clean, code-compliant, and built to last through years of use. Before closing any wall, we check the surface with a digital flatness straightedge with electronic level sensor to confirm it is flat and dry. All backing boards are cement-based tile backer board meeting ASTM C1325 Type A classification. We file all permits through the Sacramento County Building Inspection Division EPIC Online portal for all residential bathroom alteration work.
Tile Replacement and Shower Surround Remodeling
Cracked tile is more than a cosmetic problem. When grout fails, water gets behind the tile. Over time, that water damages the substrate and the wall structure behind it. We remove old tile carefully so we do not damage the framing underneath. Then we install a waterproof membrane before laying the new tile. We handle shower surrounds, floor tile, and accent work. We also help you choose tile that fits the size of your ADU bathroom and holds up to daily use. For simple tile swaps, a permit is usually not required. We tell you upfront exactly what your project needs. We remove old tile using a pneumatic tile chisel scaler to protect the wall structure behind it. New tile goes over a Schluter-DITRA uncoupling membrane set with mortar that meets ANSI A118.15 for non-sag adhesion strength. This follows the Tile Council of North America TCNA W244F wet area method, which Sacramento County references for all shower enclosure work.
Plumbing Fixture and Vanity Replacement
Older ADU bathrooms often have toilets that run constantly, faucets that drip, and vanities that take up too much space. Replacing fixtures is one of the most cost-effective upgrades you can make. We swap out toilets, sinks, showerheads, and faucets. We also replace vanities, including wall-mount options that free up floor space in smaller bathrooms. All new fixtures are WaterSense rated, which means lower water bills for your tenant or family member. If we need to move a fixture to a new location, that requires a permit. We assess the scope before starting so there are no surprises. We test every supply line with a digital water pressure test gauge with glycerin-filled dial before the job is done. Every toilet we install meets California’s 1.28 gpf maximum flush limit under CalGreen Section 4.303.1. This rule applies to all ADU fixture replacements in Sacramento County, no matter the unit type or age.
ADA and Accessible Bathroom Remodeling
If someone in your ADU uses a walker, a cane, or a wheelchair, a standard bathroom layout does not work safely. We remodel ADU bathrooms specifically for accessibility. We install curbless showers that are easy to step into. We add grab bars at the right height and location. We widen doorways if the existing opening is too narrow for a mobility device. We also install ADA-height toilets and lever-style faucet handles that are easier to use with limited grip strength. These changes make a real difference in daily safety. We handle the Sacramento County permits required for structural changes. We load-test every grab bar anchor using a torque wrench with calibrated inch-pound dial to confirm it holds safely under pressure. All bars are installed into 1.5-inch minimum solid wood blocking behind cement board substrate. Grab bar heights and clearances follow CBC Chapter 11A Section 11A-603.5, which sets the accessibility standard for privately owned residential bathrooms in California.
Bathroom Layout Reconfiguration
Some ADU bathrooms have the right square footage but the wrong layout. The toilet is where the shower should be. The vanity blocks the door. The shower is so small it is not usable. We can reroute drain lines and relocate fixtures to create a layout that actually works. We also convert half baths to full baths by adding a shower within the existing footprint when space allows. This type of work requires Sacramento County permits because drain lines are being moved. We manage the permit process, schedule the rough-in inspection, and handle the finish work after approval. We check every new drain slope using a digital pipe slope level with LCD readout to make sure water flows correctly. All rerouted lines use schedule 40 PVC DWV pipe with solvent-weld ABS fittings sized for the fixture load. We book rough-in inspections through Sacramento County Building Inspection under Plumbing Category P-1, which requires 24-hour advance notice and a permit card posted on the job site.
Shower Enclosure and Wet Room Conversion
Old prefab shower stalls crack, discolor, and leak at the base. If your ADU has one, replacing it with a custom tile shower or a modern wet room is a smart upgrade. We remove the old unit, install waterproofing on all walls and the floor, and build a new shower that fits the space. For smaller bathrooms, a wet room design eliminates the need for a separate enclosure and makes the space feel larger. We offer frameless glass enclosure options as well. Whether you want a simple clean shower or a full wet room, we design and build it to your space and budget. We set and slope-check every linear drain using a stainless steel shower slope gauge with magnetic base to confirm proper flow. The floor is waterproofed with hot-mopped chlorinated polyethylene shower pan liner at minimum 40-mil thickness. All frameless glass panels must meet CBC Section 2406.4.4 for glazing adjacent to wet surfaces, which requires tempered or laminated safety glass with a permanent etched certification mark.
ADA and Accessible Bathroom Remodeling
Mold in an ADU bathroom is almost always a ventilation problem. If the exhaust fan is weak, noisy, or vented into the attic instead of outside, moisture builds up every time someone showers. Over time, that moisture damages drywall, grows mold, and creates air quality problems. We replace old exhaust fans with quiet, high-efficiency units. We also reroute ducting to vent directly to the exterior, which is required under Sacramento County code. For bathrooms without any fan at all, we install one and run it to an exterior exit point. Title 24 ventilation compliance is included in every permitted bathroom remodel we complete. We measure airflow at the grille using a digital anemometer with CFM flow measurement display to confirm the fan works at full capacity. All replacement fans are HVI-certified ENERGY STAR exhaust fans rated at minimum 50 CFM. Under California Mechanical Code Section 504.6.1, all ducts must vent to an exterior wall or roof cap, not into the attic. Sacramento County inspects this on every permitted bathroom alteration.
Bathroom Layout Reconfiguration
A bathroom remodel is only as good as what is behind the tile. If the waterproofing layer is skipped or done wrong, water gets into the wall and the floor. That leads to mold, subfloor damage, and tile failure within a few years. We install a proper waterproof membrane on every shower and wet area we tile. We use trusted systems including Schluter Kerdi and RedGard. If we open a wall during a remodel and find moisture damage behind the old tile, we repair the subfloor and substrate before anything goes back in. This step is built into every bathroom project we do, not treated as an add-on. Before setting any tile, we plug the drain with a threaded rubber test plug with pressure gauge adapter and hold 2 inches of water for 24 hours to confirm zero leaks. All membranes follow TCNA Method B415 bonded waterproof membrane guidelines. The finished assembly meets CRC Section R702.4.2 wet area substrate requirements, which Sacramento County inspectors verify on all permitted bathroom projects.

ADU Bathroom Remodeling Questions
Do I need a permit to remodel my ADU bathroom in Antelope?
It depends on what is being done. Replacing tile or swapping out a fixture in the same location usually does not require a permit. Moving a fixture, rerouting drain lines, or adding electrical work does. We look at your specific project and tell you exactly what applies before any work starts.
How long does an ADU bathroom remodel take in Antelope?
A fixture replacement or tile refresh takes one to two weeks. A full gut renovation with permits typically takes three to five weeks, depending on Sacramento County’s inspection scheduling. We give you a realistic timeline before we start so you can plan around it.
How much does an ADU bathroom remodel cost in Antelope, CA?
The cost depends on the scope, the condition of the existing bathroom, and what permits are required. We provide a fixed-scope written quote after the assessment. You know the price before any work begins.
Can you add a shower to a half bath in my ADU?
Yes. We can convert a half bath to a full bath by rerouting the drain line and adding a shower. This works when there is enough floor space to fit a code-compliant shower stall. We assess the layout and tell you what is possible before committing to a scope.
What causes mold to keep coming back in my ADU bathroom?
Almost always, it is a ventilation problem. If the exhaust fan is weak or not ducted to the exterior, moisture has nowhere to go. We fix the root cause, not just the visible mold.
Can you make an ADU bathroom safe and accessible for someone who uses a walker?
Yes. We install curbless showers, grab bars at the correct ADA locations, ADA-height toilets, lever-style faucets, and wider doorways if needed. These are standard modifications we complete regularly.
Do you manage the Sacramento County permit process?
Yes. We prepare the permit submittal, coordinate with Sacramento County Building Division, and schedule all required inspections. You do not need to handle any of that.
Can I stay in my main house while you work on the ADU bathroom?
Yes. The ADU is a separate structure from your main residence. The work we do in the ADU does not affect your home.
How Much Does It Cost to Add Plumbing to an ADU in Sacramento?
Subterranean sewer trenching, water line tie-ins, and dedicated plumbing rough-ins for an ADU bathroom in Sacramento typically range between $15,000 and $25,000 depending on the distance to the main municipal sewer lateral, existing slab elevation, and Sacramento County permit requirements.
