What are the min and max deck thickness for installation?
We plan to mount the Lahara T4738 on our tile deck that surrounds the drop-in tub. What are the min and max thickness of the deck required in order for this to mount properly? I am talking about the thickness from top to bottom.
(Not the width of the tile surface, but the total thickness).
My plumber says we need to know this, since we are not mounting the fixtures on the tub flange, but on the outside,
Thanks a bunch! ~Jody
Thank you for your question, Jody. There are two ways that you can install the valve for this model. In a Standard Installation, the valve goes through the entire deck and has a maximum deck thickness of 2 1/2" including the plywood underlayment. In a Thick-Tile Installation, the valve is mounted on top of the underlayment and has a maximum thickness of 2 1/2" for the tile only.
Please see pages 3 and 6 of the Installation Manual for the R4707 Rough-In Valve to compare the installation types:
You can find these and other measurements in the Technical Specifications:

Does the Lahara roman tub faucet and hand shower combo include the drain? If not, what part is needed?
Thank you for your question. The faucet trim does not include a drain assembly. Unfortunately, we do not make drains for jetted or garden tubs.

can this model be installed with shower head near the middle?
Thank you for your question. The hand shower can be positioned anywhere in relation to the spout and valves, but with a maximum distance of 18 inches from the spout. The valves must be 8 - 16" on center. Please click the link below to view or download the Technical Specification of the rough-in valve for more information.

Can I use the T4738 faucet without the shower head?
I purchased the Delta T4738 Lahara Roman Tub faucet with shower head. Turns out I'm not going to be able to use the shower head with my existing valve. Can I use this faucet without installing the shower head? Thanks.
Hi Keith, Thank you for your question. You will not be able to use the T4738 trim on your old valve if it was not already plumbed for the hand shower. The spout connections are different. You will want to get the model T2738 which does not come with the hand shower instead.
