> Hi,
>
> I have a split/tri-level house and am trying to put a shower in the
> basement where a 1/2 bath alread exists. I ripped out the walls and
> the ceiling in the bathroom and found that the main HVAC supply trunk
> goes from the air handler just outside the bathroom, above the ceiling
> and down the back wall of the bathroom. The trunk does a 45 degree
> angle from the ceiling at a downward angle at the end of the bathroom
> behind a fake wall setup to hide the duct, goes down behind the wall
> and does another 45 degree angle travelling the same direction out of
> the bottom of the bathroom wall. It goes through an opening in the
> cinder block foundation out under the other side of my house that only
> has one level (the bathroom is just on the other side in the
> downstairs level if that makes sense). This trunk then supplies a
> kitchen and a family room.
>
> My HVAC problem is that where they did these 45 degree bends was not
> in one isolated corner of the bathroom or the other but about a foot
> or so away from the corner. Ideally if I could take out the whole
> duct and use this space for my shower I would be set but of course
> then I wouldn't have HVAC in my kitchen or family room. Plan B would
> be to move or replace a small section of the duct beginning in the
> ceiling, move it over as tight into the corner as possible and then
> just build a very small L shaped wall to hide the duct in the corner.
> This would give me an extra foot or so width for my shower. I
> shouldn't have a problem cutting through the cinder block but I was
> hoping that I could cut the exisitng sheet metal duct from somewhere
> in the ceiling and replace just a section of it with flexible duct.
> This short flexible duct would then be spliced back into the existing
> sheet metal duct work under the house. I am guessing the run would be
> no longer than 10ft. Is splicing flexible duct doable or should I
> replace this section with matching rigid sheet metal duct? The run
> from the air handler to my kitchen is 8 ft at the most, but the bend
> going down the wall adds to this length. The kitchen and livng room
> area are at the most 500 sq ft. There is a separate trunk handling
> that won't be touched handling the rest of the house. Thanks in
> advance!
