When planning the wall of sliding doors for the basement, we knew that we wanted to be able to access both the washer and dryer at the same time; in order to make this happen, we had to add another 3-4 inches onto the span of the sliding doors. In doing so, we reduced the size of the bathroom by this same amount. Accordingly, as it stands right now, a standard vanity (22" deep) would be 24" from the front of the toilet and 20" from the end of the tub. This is acceptable, but makes the space kind of tight and uncomfortable, so we started looking for a vanity that does not take up as much space.
In order to accomplish this, we need to find a vanity that is not very deep (16-19") and/or that takes up less space than a cabinet style vanity (i.e. pedestal sink). To throw another wrench into this decision, we plan to have some built-in linen storage in this bathroom, so that needs to coordinate with everything.
Option 1: Our favourite look right now is the Retrospect Console Table from American Standard. It would definitely meet our aesthetic and space requirements, and would match multiple wall cabinet options, but it needs to be custom ordered and is a little bit outside our budget ($700ish, plus the matching toilet is pricey).
Option 2: We also like the look of this pedestal sink. This would cost about half the price (or less) of the above console table. I know pedestal sinks aren't typically used in a three piece bathroom, but the added built-in storage should make up for the lack of cabinetry, so maybe that is not a big deal?
Option 3: Another option we are looking at is modifying a kitchen cabinet from Ikea (maybe the Adel?) to fit one of their smaller sinks such as the Odensvik. This type of cabinet option would not seem as spacious as the above options, but has a good depth of 18.75" and could obviously coordinate well with matching wall cabinets.
Option 4: This is probably unlikely, but we are actually considering using the sink that was in the upstairs bathroom when we bought the house. It has been sitting in our garage for 2.5 years (didn't have the heart to throw it out) and is in great shape, but we would probably need to spend about $300 to re-finish the sink and re-plate the legs. The question here is whether or not it suits the style that we are going for (probably not).
