Almond is neutral enough that you should be able to use an accent color with it. I would start with the fabrics/textiles (a shower curtain and runner bathmat.) Then match paint for the vanity to that color. Repeat in some accessories on the countertop and some art on the wall opposite the toilet or on the back of the bathroom door. Navy or red come to mind. If you are selling within 5 years, consider white for the vanity and white towels and shower curtain for a crisp, fresh feeling ready for market. When budget allows, you can replace the strip lights.

For fun and not much expense, I would replace the sink with a Mexican/ Talavera one and pick a color from the sink for shower curtain and bath mat.

Talavera Sink

I enjoy an almond bathroom...I'm probably only one of a handful here who do :-/

I think navy and almond are lovely together...
