It doesn’t seem to matter what season it is—even when it is 90 degrees outside, your bathroom always manages to make you feel like you took a trip to the North Pole.  Inside the shower, everything is fine, but that shower must end.  And when it does, it is time to face the chill of the tile.

You tried a space heater, but it took up too much room.  So, instead, you bought the fluffiest robe you could find and resolved yourself to the mad dash from your bathroom to your bedroom.  But it doesn’t need to be that way

With the Amba Siro  towel warmer, you can keep your towels and robe nice and toasty.  Plus, the warmer will radiate heat into the bathroom, taking the chill off of the tile and creating your own, private sanctuary.

Works well

Takes about 30 minutes to get hot enough to warm towels

Great Towel Warmer!

We love this towel warmer. It was the perfect addition to our master bath. OnlyTowelWarmers was superb, great customer service and a great price. I highly recommend them.

Jim, Great to hear that the Amba Sirio is serving you well! We appreciate your business. Michael

Love the Amba S2921 So Far

Bought the Amba S2921 because we wanted to control the heat, and we wanted the bars to be closer together. (Some of the other popular units seemed to get too hot, and the bars looked far apart. Since the towels touching the bars is how it works, we wanted closer bars.) Plus we liked the width for 2 towels, and the more compact feel. Bought (separately) a Century in-wall digital timer so we could have it turn on and off automatically in the morning. Had an electrician install it all, which he did without messing up any walls, which I appreciate (cost about $300). So far, everything seems great. Looks nice on the wall. Ordering was easy and delivery was quick. Got this as a birthday present for my wife, and she loves it (as do I). The towels get nice and toasty. A well-deserved 5-star rating.

Love it!

Great towel warmer. Needed some help on the install and customer service was very responsive and helpful.
