My house came with T2738 (no handshower). What are the steps/parts to get the handshower?
Thank you for your question, Vanessa. If you have a 5th hole in the tub and access below the deck, a transfer valve and hand shower can be installed such as the RP14979 or RP33791LHP.
Otherwise, you would need to replace the valve and trim with an R4707 and T4738.
Best regards, Jon

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:
