A $25,000–$40,000+ budget is a realistic range for many of the full bathroom remodels we’ve completed in Aliso Viejo.
Cost can vary depending on;
For bathrooms that need a full renovation, we coordinate the project from demolition through final finishes. The scope can include a new shower or bathtub, waterproofing, tile, vanity and countertops, plumbing fixtures, lighting, electrical, ventilation, flooring, drywall, painting, mirrors, glass, hardware, and finish work.
We can evaluate whether the existing shower, tub, vanity, storage, and fixture locations are making the best use of the room. Where appropriate, the remodel may include a larger walk-in shower, redesigned vanity, freestanding tub, additional storage, relocated fixtures, or changes to the bathroom and adjoining closet configuration.
Replacing an underused bathtub with a walk-in shower can create more usable shower space without increasing the bathroom footprint. A complete shower remodel may include new plumbing, drainage, waterproofing, tile, niches, benches, fixtures, lighting, ventilation, and glass.
Depending on the floor plan, this may involve incorporating space from a closet, hallway, or adjoining area; relocating the vanity, toilet, shower, or tub; or reconfiguring the bathroom and closet together.
If you’re planning to remodel two or more bathrooms, or the bathrooms are part of a larger Dana Point home renovation—we can plan the work together instead of treating each room as a separate project. That allows us to coordinate materials, plumbing, electrical, cabinetry, tile, flooring, painting, and construction sequencing, including how to keep a usable bathroom available when you’re living in the home during the remodel.
A complete bathroom remodel involves more than new tile and fixtures. We coordinate the work behind the finishes and the details you see every day so the entire bathroom is planned as one project.
Whether you're enlarging an existing shower, removing an underused tub, or rebuilding the entire wet area, proper preparation is essential.
Depending on the project, we can include:
We coordinate the plumbing, drainage, waterproofing, tile, and glass together so the finished shower is built correctly beneath the surfaces as well as above them.

Your remodel may include:
We plan the vanity around available space, plumbing locations, storage needs, lighting, and comfortable circulation rather than simply replacing the existing cabinet with one of the same size.

Once the underlying construction is complete, the final materials bring the bathroom together.
That can include:
For primary bathrooms and larger renovations, we coordinate these selections so the tile, cabinetry, countertops, fixtures, and lighting work together rather than feeling like separate upgrades.
Learn MoreA complete bathroom remodel typically requires approximately:
3–5 Weeks of Construction
Projects involving significant layout changes, plumbing relocation, custom materials, or additional construction can take longer.
Planning also occurs before construction begins. Depending on the project, this can include material selections, ordering, permit review, and other pre-construction requirements.
Most complete bathroom remodels require a permit.
According to the City of Aliso Viejo, a permit is generally required when the project includes:
Replacing or relocating vanities
Moving sinks or toilets
Replacing or relocating tubs and showers
Plumbing changes
Lighting or electrical changes
Removing and replacing wallboard
Minor work such as painting, replacing mirrors or towel bars, or replacing flooring by itself generally does not require a permit.
When required, Kol & Co. can coordinate the permit documentation, construction, inspections, and final completion.

We evaluate the existing bathroom, discuss your priorities, and determine whether the project is primarily an update or whether the layout should also be reconsidered.

We develop the scope around the shower or tub, vanity, storage, fixture locations, tile, lighting, plumbing, and finishes.

When permits are required, we coordinate the applicable documentation and prepare the project for construction, including selections and material ordering.

We coordinate the applicable demolition, plumbing, electrical, framing, waterproofing, drywall, tile, cabinetry, countertops, flooring, fixtures, glass, painting, finish work, and inspections.

The project concludes with final details, applicable inspections, and a walkthrough of the completed bathroom.
We work with homeowners throughout Glenwood, Westridge, Pacific Ridge, California Summit, Canyon Vistas, Talavera, and surrounding Aliso Viejo communities.
