Rated 5 out of 5 by from Very Classy Look in our Master Bath I've had the faucet for a few years now, and it still looks like new, and it fills the tub quickly with great flow rate. Glad we bought this!

Rated 5 out of 5 by from Great Delta product We bought this faucet about a year ago. Quality faucet for our whirlpool tub. Solid and easy to use. Handheld shower is a little awkward since it leans forward. We trust Delta.

Rated 4 out of 5 by from Difficult directions Directions are not always clear, and the illustrations are small and not keyed well. The trim ring on the hand held faucet was shipped with the incorrect part....not apparent until the actual install was started. Had to go online to find a parts list to identify the problem.

Rated 5 out of 5 by from Good looking! This faucet set is sleek and fits nicely on the narrow deck surrounding my new tub.

Rated 3 out of 5 by from How do you install it. the handles seem to require hand tightening. Why isn't there a nut and washer that you can tighten before screwing on the base? The instructions don't address the stem installation which was confusing.

I have a Delta roman tub faucet that looks like the Lahara. I am wondering how to tighten the spout. It feels loose. There is an opening at the base, but it is not an allen wrench fit like the hot and cold handles. Is there a special tool needed?

Asked by: Scott
Thank you for your question, Scott! The set screw for the handle takes a 3/32" (2.38mm) allen wrench whereas the spout uses 1/8" (3.17mm). Best regards, Edward

My house came with T2738 (no handshower). What are the steps/parts to get the handshower?

Asked by: Vanessa
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. https://www.deltafaucet.com/search-results?searchTerm=transfer+roman Otherwise, you would need to replace the valve and trim with an R4707 and T4738. https://www.deltafaucet.com/bathroom/product/R4707 https://www.deltafaucet.com/bathroom/product/T4738 Best regards, Jon

Can you please tell me the flow rate for the tap portion? Please note I am not asking about the flow rate on the hand shower. Also what is the reach of the tap?

Asked by: Susan
Thank you for your question, Susan! The R4707 rough in valve that is typically used with this model has a flow rate of 18 GPM @60 PSI . Depending on the PSI to your home you may get a rate of approximately 15-18gpm from the tub spout. The technical specifications sheet for this model includes a flow rate chart to help determine the rate for both the spout and hand shower. The spout reach is 8 1/2" (216mm). https://media.deltafaucet.com/SpecSheet/DSP-B-T2738%20Rev%20E.pdf Best regards, Edward

Hello. I am installing 1 1/4” quartz on the tub deck for our installation. I’ve read the directions and think the thick tile installation method will be the best. What’s the max dimension the valves can extend above the quartz??

Asked by: Jeff
Hello Jeff, Thank you for your inquiry! The rough-in valve is designed to set 1 3/4" (45 mm) above the finished surface for the Lahara Roman Tub Trim T4738-SS model. https://media.deltafaucet.com/SpecSheet/dsp-b-r4707_D.pdf Best regards, Tanya

We have the Lahara faucet on our whirlpool tub and was wondering if the builder forgot to put the buttons on the handles to signify which is hot and cold or doesn't it have them?

Asked by: PatC
Hi, PatC! Thank you for your question. The Lahara Roman Tub T4738 is designed without button covers for the handle assemblies. Best Regards, Rosanna

How long is the sprayer hose?

Asked by: Justin
Thank you for your question, Justin! The hand shower hose is 59" long. This will connect to the leader hose on the R4707 valve, which is 24". 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, surrounding tile. Thanks a bunch! ~Jody
Asked by: 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: https://media.deltafaucet.com/MandI/80162%20Rev%20C.pdf You can find these and other measurements in the Technical Specifications: https://media.deltafaucet.com/SpecSheet/DSP-B-R4707%20Rev%20D.pdf Best regards, Jon
