Welcome to the One Room Challenge
As first time participants in the One Room Challenge, I’d say that we are beyond excited to share what we have planned to tackle over the next 8 weeks! If you’re new here, WELCOME! You can learn more about us here.
Certainly be sure to follow us on Instagram for behind the scenes progress and updates!
So what is the One Room Challenge? It’s a biannual event held every April and October. Each round 20 design influencers are selected to take the challenge of being featured designers and transform one space in just 6 weeks!
(However, two additional weeks have been added to this round as supply and demand needs have been altered during the pandemic.)
Additionally, guest participants like ourselves are likewise invited to transform any given space during the same time frame. Each week designers and guest participants share their progress via the One Room Challenge platform as well as blogs and all forms of social media. Be sure to join us each week to check on our progress!
Of course if this isn’t exciting enough, two lucky guest participants with a blog will be selected by the editors of Better Homes & Gardens (who is the official media partner of this event) as Featured Designers for an upcoming ORC event! Surely that would be an unbelievable opportunity!

One Room Challenge: Jack & Jill Bathroom
For this round of the One Room Challenge, we plan to completely transform the unfinished basement space for our Jack & Jill bathroom. The bedroom to the left of the Jack and Jill bathroom has been finished for a few years. It’s currently used as our home office and craft room. All remaining areas of the basement are currently in progress.

Design Inspiration
The design inspiration for this space comes from my love of all things coastal! As mentioned in my home tour, when building we opted to stick with many of the builders grade finishes to keep costs down. Despite this, we plan to upgrade these finishes at some point. Whereas finishing the basement from a blank slate is the perfect opportunity to incorporate upgraded finishes right from the start!
This Jack and Jill bathroom will boast a combination of styles. From the timeless look with navy subway tile, a modern flair with mixed gold and black finishes, natural wood elements and unexpected vintage accessories.
Undoubtedly I can’t wait to bring all these elements together to create this calm coastal vibe! Certainly upon completion, this will be the most high-end bathroom in our home! Although the remaining basement projects take precedence, personally I think the master bath should fall next on the docket! Don’t you?

one room challenge: unfinished bathroom

Over the next 8 weeks you’ll see this empty space transformed. In its current condition, the bathroom has primed walls. Everything else in this space needs to be finished!

The right side of the bathroom will include a large vanity and toilet. Through the second doorway you’ll find the shower and another vanity.

A functional board and batten design will be added to the wall connecting these two spaces. This will provide the perfect area to install hooks for towels.

As mentioned previously, the shower surround will feature navy subway tile with white grout. The shower niche will also include a beautiful Newport scale beach tile.

The flooring throughout the space will be a 2″ white hexagon tile with black grout to further accentuate the high contrast in this space.

Finally, a smaller vanity will also be located on the far left end of the bathroom.
Tentative 8 week work flow schedule
- Week 1: Introduce the coastal inspired vision board and plan for progress. Gather remaining supplies.
- Week 2: Paint walls and ceiling white. Paint and install navy shiplap behind each vanity.
- Week 3: Install shower tile.
- Week 4: Grout and seal shower tile. Begin tile floor installation.
