Sonia makes narrow vanities, but they are pricey. We had a local guy make us a pretty close replica (a little taller) out of walnut, and it was ~1/2 the cost.

We did end up ordering the Sonia sink top, because we needed a shallow sink in order to maximize our storage underneath (didn't want a vessel sink), and we just really liked it, too!

This company makes small vanities in various sizes and with a choice of finishes.

I don't have firsthand experience; I only saw one briefly at a showroom. Also, I don't know how much they cost. I'm still waiting for the bath place I talked with to give me an estimate.

I was able to find a lot of vanities in 18/19" depth. The tricky part for me was my length at 43.5"-ugh. Believe it or not, I actually found some in my size by searching the internet by the sizes and bath vanity. How long is your vanity?

Here is an old thread about 18" deep vanities: http://ths.gardenweb.com/forums/load/bath/msg0910324722074.html

Even Home Depot had 18" deep vanities but the trick is the length. If you are flexible there, you will have many choices. I thought mine was 19" but then realized the top hung over making it really 18" but found many new glass ones that would fit in the space and even some from costco that could fit the depth but not length. http://www.costco.com/Common/Category.aspx?whse=BC&Ne=4000000&eCat=BC:114:1240:4304&N=4000382&pos=0amp;ViewAll=44&Nr=P_CatalogName:BC&cat=4304&Ns=P_Price:1::P_SignDesc1&lang=en-US&ec=BC-EC10618-Cat1240&topnav=
Some of these are really a bargain because they include the sink too. Also, there are many with curved fronts that are only 18 on each side but then the middle of the vanity bows out giving more room for a bigger sink and more storage underneath.

In the end, I saved my old cabinet and am having a painter redo it, changing the hardware and just had a new granite top installed Friday and I love it! My door opens right at the vanity so that made it even more difficult to determine exactly what would fit.

Be aware too of the kind of sink you want and make sure it will fit the vanity you buy. That is very narrow and the sink choices can be tough expecially if you want an undermount. A wall mount faucet will give you more counter space too. I ended up with a vessel sink and faucet because of the plumbing and also the cost of fabricating the granite. $20 per hole for the faucet and sink drain holes versus $250 for the sink opening.

I realized that my "old" cabinet matches all the kitchen cabinets and also the other 2 bathroom's cabinets so I am glad that I kept it in the end, just something to think about as well. Good luck and sorry I don't know about the bath tub but get a new one-1931? it's time!

I'm going to buy a narrow dresser and use that as a bath vanity for my narrow bathroom, but Home Depot has a number of Pegasus vanities for very little $ that are quite shallow--and some even come with drawers!

Don't discount custom. Sometimes, it's better quality for less money than many overinflated brands.

For the tub, the best bet would be a drop-in design. That way, you wouldn't have to have a short wing-wall to cover a three-wall alcove style, and you wouldn't have to pay the kind of price that something as unusual as a two-wall alcove would demand. Don't forget your local cultured marble folks. Sometimes, they're surprisingly cheap, and I like cultured marble FAR better than an acrylic tub.
