You could go either way, but I am not crazy about how it sticks up. To me, that takes away from your streamlined look and so I'd say, if you like the sink, then lower the cabinet. Or, choose a different style of sink that doesn't add another 1-2" to the height.

I agree about the sink "sticking up". I wasn't expecting that look. Thanks for your input.

To me, it kind of depends on how deep the new sink is. If it can easily hold an entire laundry load of water without overflowing (in case of plug-up), then go ahead and get an undercounter sink. But if an undercounter sink cannot hold that much, I would worry about being outside, or in bed, or away from home while a load is washing. Having the ability to drop a load in on the way to work and take care of it when I get get home is one of the perks of having a home laundry.

The sink looks perfect and novel and perfect for tall folks. I am not tall but I would get used to that. I would like one of your tall girls if she is tall enough to use that sink. I wish to dance both the mountain flat foot and a great slow waltz to Patsy Cline with her. :)

BTW if how high to rough in the plumbing for a tradtional height Laundry sink, I seem to have missed it. Sadly I was a plumber many many years and forgot. I think the sink may be 30 inches high for laundry and if a P trap is used, I think the rough is around 14 or 16 in oc from floor level. PLEASE do not quote me on this or use it as accurate info as it is memory only and some place we will find the answer on G or B.
