Dennis: 
I am very interested in the 19.5" OTB. Thanks for posting the dimensions. 
For my built in application, I would need to get one without the legs, are you able to provide the unit without the legs? 
Without the legs, what would the Floor to Lip dimension be?  I need it to be ~27",  in order to have it work for my particular set up. 
I would prefer to get it in the textured version, without tiles. Would that be available?
