From Larger Walk-In Showers and Better Layouts to Complete Bathroom Renovations, We Handle Design, Plumbing, Permits, and Construction
Licensed • Insured • Bonded • 15+ Years Experience • Design-Build Experts • Serving Southern California
If your bathroom feels cramped, outdated, short on storage, or simply doesn’t work the way you need it to, replacing the tile isn’t always the answer.
Maybe you want to turn an old tub into a larger walk-in shower. Maybe the vanity is too small. Maybe you’d like to move the toilet, add a double vanity, or borrow space from an adjoining closet to make the bathroom larger.
Before deciding what the new bathroom should look like, we look at what isn’t working now and what can realistically be changed.
Kol & Co. is a licensed, insured, and bonded design-build contractor with 15+ years of experience handling complete bathroom remodels, including layout changes, plumbing and electrical work, showers, waterproofing, cabinetry, tile, lighting, permits, and final finishes.

For the full bathroom remodels we typically take on, homeowners should generally plan for approximately:
$25,000–$40,000+
The final cost can be affected by the bathroom size, existing conditions, shower or tub design, plumbing relocation, layout changes, cabinetry, countertops, tile, fixtures, electrical work, waterproofing, material selections, and permit requirements.
That’s why we prefer to see the existing bathroom before discussing a detailed project estimate.
Ready to replace everything? We can take the bathroom down to what needs to remain and rebuild it with a new shower or tub, vanity, countertops, tile, flooring, lighting, plumbing fixtures, ventilation, waterproofing, and finishes—all coordinated under one project.
Want your primary bathroom to work better for two people? We can enlarge the shower, add a double vanity, improve storage and lighting, remove an unused tub, relocate fixtures, or reconfigure the room to make better use of the available space.
Want to get rid of an unused tub or make your shower larger? We can build a walk-in shower with new plumbing, waterproofing, tile, frameless glass, niches, benches, handheld fixtures, and other features based on your space and how you want to use it.
Need more room or a completely different layout? We can evaluate moving the toilet, shower, tub, or vanity, changing door locations, removing walls, or expanding into an adjoining closet or available space to make the bathroom work better.
Remodeling more than one bathroom—or updating the kitchen and other areas too? We can coordinate the bathrooms, plumbing and electrical work, flooring, structural changes, finishes, and construction schedule as one larger renovation instead of treating every room as a separate project.
A complete bathroom renovation involves both the finishes you see and the work that makes those finishes perform correctly.
A shower needs to be built correctly before the first finished tile goes on.
Depending on your remodel, we can handle:

We plan the vanity area around storage, available wall space, plumbing, lighting, and how the bathroom is actually used.
Options can include:
These are easy to overlook when you're looking at inspiration photos, but they have a major impact on the finished bathroom.

Once the room itself is built correctly, we coordinate the finishes that bring everything together.
That can include:
For the full bathroom remodels we typically handle, construction generally takes around:
3–5 weeks
That can vary depending on the scope.
Layout changes, plumbing relocation, inspections, extensive tile work, custom glass, material availability, and conditions uncovered during demolition can affect the schedule.
It depends on what you’re changing.
A bathroom remodel involving plumbing, electrical, mechanical, structural, or significant layout changes may require permits.
For example, the requirements can be different when you’re simply replacing finishes versus relocating a shower, moving a toilet, changing electrical work, or expanding the bathroom.
We review the scope during planning and coordinate applicable permits and project documentation before construction.

We visit your Santa Ana home, look at the existing bathroom, discuss what isn't working, and talk through the changes you're considering.

We develop the layout and coordinate the shower, vanity, fixtures, materials, plumbing, electrical, and other project details.

When required, we coordinate applicable permits while confirming the scope, selections, and construction planning.

We manage demolition, plumbing, electrical, waterproofing, tile, cabinetry, fixtures, painting, and other work included in your bathroom remodel.

We review the completed bathroom with you and address remaining details before completion.
We work with homeowners throughout Floral Park, West Floral Park, Park Santiago, Washington Square, Wilshire Square, Heninger Park, French Park, Fisher Park, Morrison Park, and surrounding Santa Ana neighborhoods.
You don’t need to know whether the toilet can move, whether there’s room for a larger shower, or whether taking out the tub is the right decision.
That’s what we can help you work through.
We’ll look at the existing bathroom, listen to what you’d like to improve, and discuss what may be involved in creating a space that works better for you.

Construction generally takes approximately 3–5 weeks for the bathroom remodels we typically handle. More complex projects involving major layout changes or unexpected existing conditions may take longer.
Potentially. Depending on the floor plan, we can evaluate expanding into an adjoining closet, bedroom, hallway, or other available area. We also consider whether reorganizing the existing footprint could solve the problem without expanding the room.
Yes. Depending on the existing space and plumbing, we can replace a tub with a walk-in shower and incorporate new waterproofing, tile, glass, fixtures, niches, benches, and other features.
Often, yes. Toilet relocation can be more involved than moving some other fixtures because of the drain requirements and existing framing. We evaluate the proposed location before finalizing the layout.
