<P>Cat here, great site! the hot tub is out!  Got to have one of those !!  anyone know how  volcanic ash adds water proofing to the quick lime cement?  Is this the same ash that is used on the roads from coal burning? Maybe this is just the stuff for setting that granite floor!  Thank you </P></DIV>

<DIV></DIV>>Some time ago, PBS had a series called "Secrets of Ancient 
<DIV></DIV>
<DIV></DIV>>Civilizations", and one of the programs was on building a Roman Bath. It 
<DIV></DIV>
<DIV></DIV>>was a really good show. 
<DIV></DIV>
<DIV></DIV>> 
<DIV></DIV>
<DIV></DIV>>I don't know if/when they may re-run the series, but it may be possible 
<DIV></DIV>
<DIV></DIV>>to buy a tape of the show. It really was fascinating how they heated the 
<DIV></DIV>
<DIV></DIV>>bath houses.

<DIV></DIV>
<DIV></DIV>> 
<DIV></DIV>
<DIV></DIV>>Basically, the floor and walls contained hollow tiles. A fire was built 
<DIV></DIV>
<DIV></DIV>>under one edge of the building, and the hot air was allowed to flow 
<DIV></DIV>
<DIV></DIV>>through the hollow tiles under the floor, and up the inside of the 
<DIV></DIV>
<DIV></DIV>>walls, to vent out at the eaves. The same fire was used to heat the 
<DIV></DIV>
<DIV></DIV>>water in a large boiler for the bath itself. The website doesn't show 
<DIV></DIV>
<DIV></DIV>>everything, but the show itself was very informative. Obviously this 
<DIV></DIV>
<DIV></DIV>>type of technology relies on a lot of firewood, but the simple beauty of 
<DIV></DIV>
<DIV></DIV>>the design was inspiring.
