For Nicole's next project, it's gonna be sink or swim! The indoor pool that Nicole's grandfather built by hand is getting a much-needed refresher. First up, the safety and mechanical systems of the pool need to be overhauled to meet modern standards. The beautiful cedar ceiling and aquamarine walls are original so there is no way Nicole will change those, they just need a good wash and some new paint. In the biggest design challenge of the entire project, Nicole boldly replaces the original doors, which had been ruined with age, with giant glass garage doors to let in light and views of the surrounding countryside.
