Manhattan Summary

The Manhattan sets the standard for all luxury hot tubs. It accommodates six adults quite comfortably with a choice of up to eight seating areas. Every person can experience a full range of massage. The extra-long, reversible lounge offers two unique therapy experiences, each with an individual head rest and a set of lighted grab bars. The raised bench at the center of the lounge makes it easy to read a book or listen to music. Two seating areas across from the lounge provide generous leg room in the oversized foot well. Both corner therapy seats feature wrap around arm rests, lumbar support, and deep soaking. While both seats are identically contoured, each has a unique set of jets. The seats are angled for easy conversation as well, and separated by a built-in ice bucket and convenient shelf area.

Manhattan is rated 4.0 out of 5 by 15.
Rated 5 out of 5 by from Great Source of Relaxation Had the tub delivered on December 23 and had it up and running within 5 hours of delivery. Was a little worried when I read a review here about the sitting heightafter I ordered. I'm 5'-4" and have no problem with the seat heights. Corner seats leave me submerged up to my neck and side seats at chest height. The number of adjustments that can be made are incredible. Should have ordered one years ago.

Rated 5 out of 5 by from Manhattan Gold My wife and I looked at tubs for quite a while and I really liked the quality and design of the tub. Also, when my site prep fell behind, I was very appreciative of the delivery team keeping our tub in the warehouse until we were ready for delivery. I was impressed with the ease of the connection and startup, but is was all made worthwhile when I saw the smile on my wife's face when she moved around all the different stations and adjusted the controls until she sank back into the chair that is now "hers"! The controls allow customization if you wish but are intuitive for quick use and operation has been fantastic. We are very pleased thus far with all aspects of use and operation and am very, very pleased with the quality...I've been converted from a sceptic to an advocate!

Rated 1 out of 5 by from Fuse Problem 1. After one year I had to replace a pump $$$... 2. Blows a fuse every 2 weeks $$$... 3. I have had countless techs come over to fix the problem $$$... 4. One star because it simply does not work--FOR ME... 5. Consider yourself lucky if your Manhattan Diamond works well ..

Rated 3 out of 5 by from Not my first tub, not the best! The guy that delivered this said this would be the last tub I would ever buy. If I had not owned other brands previously, I would say that yes, I would never buy another tub again! It is too deep, ( I am 6'2" with a taller than average sitting height). The controls are confusing and don't have obvious stops, so that when turned, they continue beyond a useful position. When I try to cool the temperature of the tub, the system shuts down whenever the temperature gets more than 2 degrees above the set temperature, which happens quickly with the way the tub is designed to heat itself. This would not be a problem where the weather is always cold, but in a climate where the temperature gets warm, no one wants to get into a tub/pool that is almost as hot as the outside air!

Rated 5 out of 5 by from Manhattan Diamond Package Hands down the best hot tub manufacture around. The product you receive is top notch and makes for great therapy and entertainment. My family and I are so happy with the Manhattan Thermospa Hot Tub. We upgraded to the built in stereo system and Deluxe LED lighting system. What a treat! I had purchased a Thermospa in 2001, but sold it with the home in 2009. I missed it each and every day. I purchased this hot tub late 2014 and we are defiantly friends and family's first choice in hosting a party or get together, as they all bring their bathing suits. After owning a Thermospa hot tub, and seeing the others at the store or online, there is no comparison. Thermospa will be apart of the family for many years to come and they back that up with there untouchable warranty!

Rated 3 out of 5 by from Manhattan Diamond We ordered our tub in February 2014 to be delivered June 2014. We purchased the Ozone filtration system also and the steps to match the tub. Our tub was not up and running until mid September (we built our building around the tub!). I cannot say I am thrilled about the filtration system, but maybe it will just take a while longer for us to tweak it to where it works well. The tub itself is great - I enjoy sitting in it, the service on the other hand was extremely disappointing. I would truly look very hard elsewhere before I ever bought another ThermoSpa.

My husband works a swing shift and after night shift, enjoys relaxing in the spa listening to his favorite music and tends to sleep better after a good soak.
