I don't think you need an accent color. Keep it all in the off white/cream family. Very soothing.

Hi Beth! Your bathroom is gorgeous! Some accent color suggestions would be a true red or vermillion for a distinct accent color. On the contrary, a lilac, muted teal, sage or variations of light blue, ivory/off white could be a subtle, earthy accent. Hope this helps! Best of luck!

I agree with Rachel in that I’d go with off white towels. I’d add some plants to the decor since it has a very organic feel to it. An orchid would be pretty at the sink.

Same color as either the walls or the shower tile.

Very nicely done bathroom by the way...

Really good looking bath. I would find some dark gray or white towels. I don't think you need an accent.

This towel from LLBean is really great. It is premium organic cotton and lasts for years. Antique white, white, vapor gray or feldspar (shown at the bottom) would work in you space.
