What Does a Three-Master-Suite Remodel Really Cost in Bothell? A 22-Week Project Journal - General Contractors Washington State

Q: How much does a master suite remodel cost in Bothell?

This three-master-suite Bothell project totaled $328,828 including tax — roughly $100,000–$115,000 per suite for full bathroom rebuilds with mid-to-high-end finishes. Layout changes, tile scope, and material selections are the biggest variables.

Q: Why do remodel costs change after the first estimate?

Early estimates carry material placeholders that design later makes real, and homeowners add upgrades mid-build. On this project $74,170 was finish-material selections made during design and $21,527 was signed change orders.

Why did the price change from the first estimate?

This is the question homeowners ask most, so here’s our honest answer. The June 2025 estimate of $192,649 was written before design, with finish materials carried as a rough $15,000–$25,000 placeholder and a stated range of “about $240,000 after tax.” Design happened: the owners chose a Ferguson fixture package (73 items), KraftMaid cabinetry, designer tile in all three suites, and a quartz slab — $74,170 of real selections replacing the placeholder. Then, mid-build, they added upgrades they loved — cove lighting, a Level-5 finish, premium paint — as signed change orders totaling $21,527, two of which were actually credits back to them. Every week’s post below shows exactly where the money went.

Frequently asked questions

How much does a master suite remodel cost in Bothell?

This three-master-suite project totaled $328,828 including tax — roughly $100,000–$115,000 per suite for full bathroom rebuilds with mid-to-high-end finishes. A single master bathroom remodel in the Seattle area typically runs significantly less; the biggest variables are layout changes, tile scope, and material selections.

How long does a master suite remodel take?

This project ran 22 weeks of construction after 3.5 months of design and pre-construction. A single master suite typically runs 8–12 weeks on site. Multi-suite projects overlap trades, which is why three suites took 22 weeks rather than three times as long.

Why do remodel costs change after the first estimate?

Two honest reasons: early estimates carry material placeholders that design later makes real, and homeowners add upgrades once they see the space taking shape. On this project, $74,170 was finish-material selections made during design, and $21,527 was signed mid-build change orders — both documented line by line in the weekly posts.
