New Parts on models produced after 7/2/2024
Beautiful faucet and easy to wipe clean. My biggest complaint and why I would not recommend the newer models (apparently this was updated 7/2/2024) is because the flow of the water is not smooth. I have two (one manufactured a month before they made the change and one manufactured after the change). The water flow is totally different. It's great on the older one but not smooth at all on the newer one. You can see in the attached pic how the stream area is different.

A CUBIST gem!
As a remodel designer, I was looking for a distinctive silhouette in a bath faucet. The Trillian has a unique 'Cubist' hint and takes on sculptural, art object style.

Don't like the black seal
I bought this faucet and like the actual faucet but think it's tacky that the black rubber piece shows. In my opinion the faucet should be flush with my granite and this piece makes the faucet look cheaper than it should.

Sleek Design
This Delta faucet is very well made. The design is extremely modern and sleek. I am proud to have this installed in my home. I have not installed yet but looks very easy to do. Delta also guarantees products.

Sleek Designed Faucet
I love this faucet design! it works really well with my bathroom update. Very modern feel.
installing was slightly challenging as it has a bit of a different setup than i'm used to. I've never installed a faucet with the intakes attached on a unit directly.
nothing crazy but I felt slightly more challenging than other faucets i've used. but the look and feel of the handle makes up for it!

Very nice faucet!
This is a very nice, modern single hole faucet. We used the Trillian in our son's bathroom and it is amazing how something as simple as a sink faucet can finish a room. It really elevated the look. The finish is so nice and doesn't show fingerprints. We are super happy with it!!

Q&A
Hi…Is there any way to change the flow rate on these beautiful faucets? I have the original stainless steel unit, but the water flow is oh so slow! Thanks, Jae
Hi JaeJae,
Thanks so much for contacting Delta Faucet Company!
The TRILLIAN™ Mid-Height Bathroom Faucet MODEL#: 643-SS-DST has a maximum flow rate of 1.2 GPM @ 60 psi. It is possible that a flush could resolve this issue. First, shut off the hot and cold-water supply to flush the supply line. Remove the hot supply line from the shut-off valve and place the line into a bucket. Open the handle to the fully open middle position, and then turn the cold supply back on for one minute. The cold water should flow through the faucet and out of the hot supply tube. Reconnect the supply line and repeat with the second line. If this does not help, please let us know.
Please reach out with further questions!
Best Regards,

How do you change the cartridge in a Delta Trillian sink Faucet? After removing the handle, one assumes the cartridge is located behind the 1/2 round chrome ball. There is no place to grab on the smooth chrome 1/2 ball without damaging the chrome piece.
Hi Paul,
Thanks so much for contacting Delta Faucet Company!
The TRILLIAN™ Mid-Height Bathroom Faucet MODEL#: 643-DST cartridge can be changed by removing the handle, then bonnet nut and cap first. After that the cartridge can be pulled straight out and replaced.
Please reach out with further questions!

Do you have a larger black stainless baseplate that will cover a 3 hole granite countertop? The baseplate that comes with this faucet is too short, only 6 inches and does not cover the holes. I need one at least 10 inches wide, but in black stainless.
