Initially, the plan was to add double sinks to allow for greater flexibility when getting ready for work in the morning - the layout would have looked something like this:

With little space to work with, the plan was for two 28" vanities and a linen tower in between the sinks and toilet to replace storage space lost when removing the closet

The double sink layout would have meant removing the linen closet, moving the bathroom door down the hall, installing additional plumbing and lighting, not to mention the extra cost of two vanities, sinks, sink fixtures and lights. 

After a lot of thought, my clients decided to stick with the existing layout to avoid additional cost and work (they were doing the work themselves) that may not generate a sufficient return when they sell the house in a few years. Once the decision was made to stick to the original layout, we shifted our focus to finding ways to improve the functionality of the space in the morning.

Here is the design plan:

• We built the entire plan around the clients main wish which was for a black, modern styled vanity (unfortunately, lead times forced them to pick a different, and much more expensive vanity at the last minute, but I think it was money well spent)
• The walls are painted in Sidewalk Gray by Benjamin Moore - a very clean gray with ever so slight blue undertones - we went with this shade because there's nothing worse than a gray that feels blah and institutional
• Initially, we planned on 2" carrara marble hex flooring, however also due to lead times, we switched to 3" which looks fabulous (plus, bigger tiles = less grout and less grout = easier to clean)
• My clients really wanted some sort of border in the shower, so to keep the design clean and modern, we went with a gray glass subway tile border about 3/4 of the way up the wall and all the way around
• To avoid having to share the mirror in the morning, we added another decorative mirror above the toilet with a shelf for toiletries below (so far, my clients have not felt a need for the shelf - but it's an easy solution for additional storage space should they change their minds)
• We added frames with decorative paper behind the mirror to create more of an art piece and disguise the fact that two mirrors are hanging side by side (I found the inspiration for the idea, but my client made this a DIY project...turned out great, didn't it!?)
• Originally, I incorporated green accents in the plan to try and tie in the master bedroom which is next to the bathroom, however once incorporating all the shades of gray, my clients felt there was enough variation
