What’s Included in a 5×7 Bathroom Remodel?
Remodeling a 5×7 bathroom doesn’t just update your home—it enhances your daily routine. At Construction Remodeling in Bay Area, we help Castro Valley homeowners turn small, outdated bathrooms into attractive and highly functional spaces. Pricing typically depends on the level of customization, quality of materials, and structural changes involved.
Here’s what’s included in your remodel—and how each element contributes to the overall cost and transformation:

Custom Tile Installation
We install floor and wall tiles that enhance durability and style. Choose from a wide range of materials such as porcelain, ceramic, mosaic, or natural stone to create a look that complements your home.

Vanity Replacement
Whether you prefer a floating vanity for a sleek modern look or a freestanding option with added storage, we install high-quality vanities that maximize space and function.

Shower-to-Tub Conversions (and vice versa)
Whether you prefer a walk-in shower or a compact tub, we offer smart conversions that fit your 5×7 layout and lifestyle.

Flooring Upgrades
Durable, water-resistant flooring is a must in small bathrooms. We install slip-resistant options like luxury vinyl planks, stone tile, or heated porcelain floors to give you comfort and safety.

Plumbing & Fixture Upgrades
From faucets and showerheads to toilet replacements and rerouted plumbing lines, we handle all plumbing upgrades with licensed professionals.

Lighting Design & Installation
Lighting can make or break a small bathroom. We install ambient lighting for general visibility, task lighting for mirrors, and optional LED accents to highlight features like niches or tile patterns.

Custom Storage Solutions
Storage is a premium in 5×7 bathrooms. We build custom shelving, medicine cabinets, and recessed niches that keep your space organized without crowding it.

Wall Treatments & Painting
We use mold-resistant paint and waterproof wall panels to protect and refresh your bathroom. Accent colors and quality finishes add style to your compact space.
