Costco has a one piece Milim Globe Ridge Water Rdge # 386082 toilet reduced
from $280 to $164.
It has a rating of 150 MaP which is how many grams of waste it removes in a
I believe that 150 MaP is really low and that this toilet would often need
to be plunged.
They say it lhas a large fully glazed trap. The trap way Min is 1 3/4 "
It is a dual flush HET High Efficiency Toilet
Costco usually dowsn't sell junk and was considering purchasing it, if there
were any problems they have a excellent return policy, but then again do I
want to remove it and reinstall another one?
Is this junk? Should I waste my time?
1) That version of the MaP report is from March 2007, and does not
list the Costco one piece toilet in question.
Here's a newer version (January 2008), with the Costco Waterridge EL 1-
piece listed with the horrendous 150 MaP:
"...minimum (250 grams) waste removal performance...recommended by MaP
"...minimum (350 grams) waste removal performance...specified by the
U.S. Environmental Protection Agency for their WaterSense Program "
I too, saw that 1-piece toilet at Costco and thought hey this looks
great, and 1/2 the price of the Toto Ultramaxes (MaP 700) I recently
bought for our 9-unit apartment building. Glad I checked online first!
I haven't used the Toto Ultramax but at least one tenant has said they
love it, compared to the Kohler Wellworth ELs (MaP 250) they
I also was surprised Costco would carry such a badly rated
product....I would suspect this is a case of sloppy or no research
that slipped through at Costco, rather than a new trend (I hope!)
2) More accurately: "Buy a toilet MaP rated 350 or better." All but 3
of 25 Toto toilets in the 2008 MaP report are above 350...however the
Toto EcoSupreme EL 1-piece is barely passing at 350.
