Primary Suite

Christiansen Primary Suite Remodel

A luxury primary suite remodel in Lake Oswego. We moved the door to the bathroom to maximize function, created a wet room with a clawfoot tub, built a separate toilet room, and added a walk-in closet. No more carpeted bathrooms! A classic black and white motif with beautiful wallpaper finished off the new look. In the master bedroom, we swapped doors for windows, added new white oak hardwood floors, and installed a hidden door for secret access to another area of the home.

What Homeowners Say About Eight Inch Nails

When we finally decided to pull the trigger on a major master bath renovation we knew where to turn. Josh and his team did a wonderful job. His designer did a great job helping us with layout and finishes and everything turned out just the way we envisioned. He's a great communicator, always responding to messages. Our project turned out great!

Master Bath Renovation
8 Inch Nails created my dream kitchen. What was an outdated, broken and non-functional space is now a modern, updated, and functional place I love cooking in. They also transformed a basement storage space into a beautiful bathroom. Their exceptional craftsmanship will stay in my 1930s house forever!
Tiffany P.

Josh is FANTASTIC! Very capable and of highest quality construction. We have used Josh and his company over many years, from bath remodels to custom window installation. He is our go-to company for any remodeling job. Can't say enough good things!
