All waste & overflow kits that are listed with maximum dimensions are the slip joint type which have telescoping pipes for the drain and overflow riser with a compression type slip joint to adjust the size. The tub you specified is a built in tub, which means the waste & overflow kit will ultimately be concealed under the tub once everything is complete therefore even if you do find a waste & overflow kit listed for the dimensions your looking for it will do you little good when your Plumbing Inspector hangs a red tag on it for being code prohibited. The Plumbing Codes strictly prohibit using compression joint type waste & overflow and P-traps unless you will ultimately have a dedicated 12" x 12" service access panel either through an adjacent wall or up from underneath. For a concealed location you are required to use a glue-in type or if you insist on brass, a solder-in type waste & overflow kit. Personally I fail to see what advantage you might gain from insisting upon a brass waste & overflow in this application. While some people might be lulled into the notion that brass will last longer than PVC, in the real world such is not the case. The brass waste & overflow kits are constructed of DWV grade thin-wall brass tubing which is notorious for corroding through in 25 to 30 years whereas the PVC type are impervious to the acids present in DWV piping and have a nearly indefinite service life expectancy. In addition, the brass waste & overflow kits are about $150 whereas a PVC glue-in kit is generally less than $20. Of course you could get a brass solder in type kit for about $130 to $175 and an additional $50 to $100 labor for installation. The PVC waste and overflow kits principally have three main components; 1. The cast "overflow body", which is the PVC casting that fits behind the tubs overflow hole. 2. The "Tub Shoe", which is the female threaded casting that fits directly under the tub drain hole and into which the tub "Drain Basket" is screwed into. 3. The Tee. The pipes which connect the overflow body and the tub shoe to the tee are supplied by the installer from 1-1/2" PVC stock pipe an custom fit to length. The kit also contains a brass drain basket, brass overflow trim cover and whichever stopper assembly you might desire, whether it is a toe-tap, lift & turn or a lever lift type. The Danze-D490637RB you mentioned above is not a waste & overflow kit, but rather it is a waste & overflow "trim kit", which only contains the overflow cover, drain basket and the lift and turn stopper. It has no pipe or fittings to make the connections below the tub however, The dimensions of the trim kits is an industry standard, therefore you could go to your local hardware or home supply and purchase the cheapest PVC "Glue-In" type waste and overflow kit they have, then you could use the PVC components but discard the trim-out components and replace them with the Danze trim out kit and you will ultimately have the correct waste & overflow to meet code, complete with the "oil rubbed bronze" finish you are looking for all for about $75 in total.

Thank you Tib, Busybee and Aktillery. Moving the rug is on the agenda, but it's heavy and I can't do it alone. Went shopping and got some new pillows and I think they add just the right punch of color. I swapped out the Birdsey print over the fireplace and put it over the sofa for more color (it's not any bigger, but we used to have them side-by-side and might do that again.) Tib, Birdsey used to have a studio in Osterville, which is where we bought this one, after buying several of his pieces on a trip to his Bermuda studio. Are we there yet?

Your draperies are beautiful. Your headboard seems to be a bit on the rustic side, so I am wondering if you're going for a rustic or rustic-modern look overall. I think the night stands are getting a bit lost, but the lamps help brighten up the corners, so maybe you need some lightening up of accessories in the colors you choose on the night stands. I like the bench you posted, but again, I think you need to decide first on a quilt /bedspread color (and shams) and then make a decision on the bench. For the large blank wall, I wouldn't put anything in the floor, just use a large piece of art or sculptural piece. Or use 3 similar, same sized art pieces in alignment.

Maybe you're not ready to talk about lamps, but I highly recommend getting a floor lamp or a table lamp. It's really nice when you can layer your lighting. There's times when the overhead pot lights are optimal and then there's times when the cozy light of a lamp is best.
