We live in an older home and very few rooms have yet to be updated, including our 2 1/2 bathrooms. The bathrooms are so small and the entire house is lacking in storage space/closets/cupboards so the first year we lived here I used the space underneath the sinks to neatly store towels and toilet paper in baskets etc.
After growing tired of seeing the old pipes and my junk underneath our sinks I decided to make some skirts for our three sinks using a painters dropcloth. I only needed one 6X9 cloth (purchased at Lowe's for only $9.48) for all three sinks. After washing and ironing the dropcloth I measured the length and width that I would need for each sink and simply cut the fabric, leaving the already finished hem at the bottom. Our guest bathroom upstairs already had some clips under the sink to hold the skirt so I simply cut tiny holes in the fabric and hung it on the clips underneath the sink (yes, lazy I know).
Here's the guest bathroom sink: The other 2 sinks didn't have clips and I actually prefer the look of the fabric gathered a bit so I sewed a small hem at the top of the fabric and inserted a skinny piece of elastic on these skirts. I used velcro tabs to stick the skirt to the sink and nailed tiny nails into the wall on each side of the sink and attached the ends of the elastic for extra hold (the skirt actually covers the nails and elastic so you can't see it on the wall).
Here's the master bathroom sink (notice the lovely blue tile on the cabinet):
And my favorite, our powder bath sink:
I put these up a few months ago and they've held up well so far and I'm very pleased with the way they soften the look of the old and outdated bathrooms AND conceal bathroom essentials from our view.
