Annie Thornton From this shot, it looks like you could make these yourself. Purchase some quality rope from somewhere like a nautical shop, and tie a knot on either side of the drawer hole.
Here's a source for some lines for you to choose from. Let us know how this works out:
I am loving this kind of tub--generous but not so oversized that I wouldn't use it regularly, the ledges around being convenient for laying towels or sitting on.
Eichler bathrooms are truly small, but I am plotting how I could have one anyway.
This one is clean and modern. Love the soft grays too. Great light they're getting, I love that outdoor/indoor feeling.
