Custom Bathroom Remodels, Designed & Built to Last
Licensed • Insured • Bonded • 15+ Years Experience • Design-Build Experts • Serving Southern California
After more than 15 years of remodeling homes throughout Irvine and Orange County, we’ve learned that every homeowner uses their bathroom differently. Some want a larger walk-in shower, others need more storage, better lighting, improved accessibility, or simply a space that feels more comfortable and fits the style of their home. That’s why every bathroom we build starts with understanding how you live—not with a standard design.
At Kol & Co., we’re a licensed, insured, and bonded design-build contractor that manages every phase of your bathroom remodel—from design, planning, and material selection to permits, construction, inspections, and the final walkthrough. Whether you’re remodeling a primary bathroom, guest bathroom, powder room, or converting a tub into a walk-in shower, we focus on quality craftsmanship, thoughtful design, and clear communication from start to finish.

After more than 15 years of remodeling bathrooms throughout Irvine, we’ve found that most homeowners don’t remodel because they want a new look—they remodel because their bathroom no longer works for the way they live. Whether it’s an outdated layout, worn finishes, or limited storage, a well-planned bathroom remodel can improve both comfort and functionality.
It may be time to remodel if you have:
A professionally planned bathroom remodel doesn’t just update the appearance—it creates a space that’s easier to use, easier to maintain, and built to serve your family for years to come.
A complete bathroom remodel gives you the opportunity to fix everything that isn’t working—not just replace what’s outdated.
Our bathroom remodeling services may include:
From older Irvine homes that need a full update to newer homes ready for a more personalized design, we manage every step—from planning and permits to construction and the final walkthrough.
For many homeowners, the primary bathroom is the first room they use in the morning and the last before bed. If it feels cramped, lacks storage, or still has an oversized tub you never use, a remodel can completely change how the space functions.

One of the most common questions homeowners ask is:
“Do I need a permit for a bathroom remodel in Irvine?”
The answer depends on the scope of your project.
If you’re simply replacing finishes such as tile, paint, countertops, or a vanity without modifying plumbing, electrical systems, or walls, permits may not be required.
However, permits are generally required when your remodel includes:
Relocating plumbing fixtures
Installing a new walk-in shower
Moving or removing walls
Electrical upgrades
New lighting circuits
Exhaust fan installation
Window or skylight modifications
Structural changes
