Water Heater help.... Ideas on what to use

So my wife and I are remodeling our bathroom and need ideas on a water heater or heater(s).

We currently have a 60 gallon water heater (natural gas), and normally this is plenty except when running a large corner bath. With our bathroom remodel, we are doing a dual zone shower, each side with 5 shower heads....10 shower heads in all. Supply will be (2) 3/4" lines.

NORMALLY...only 1 or 2 shower heads will be used and our current hot water heater would be fine. But on the Rare occasion that my wife and I would both be in the shower at the same time, and both running multiple heads (worst case all heads), we would be sucking down close to 24 gpm.

We looked into Tankless, but none can supply 24gpm. If we went with a large 100gallon tank, it could be drained dry in 4-6 minutes. We also looked at Hybrid (tank with tankless attached), but not very much information on them or reviews.

Anyone have idea's or suggestions.....and use less shower heads is not a valid suggestion. (you and I know someone would say it).

Thanks guys/girls!!!!!

damn dude, I LOVE the amount of heads

If it were my shower, And the hot water was a concern I would bite the bullet and add
a 40 gallon water heater for half of the shower

For the GPM you are looking for, you will either need multiple units, or a tank/tankless combo unit.

Keep in mind the 24 gpm is not all hot water, it's being mixed with cold.

thanks for the replies....

I did see someone mention the hybrid idea, we had also thought that. This is the one we had in mind.

concerned a bit , since this is a fairly new concept and not many reviews on it. I wanted to also run a Recirculation unit, however concerned with a tankless combo it might be running all the time if I do. Takes a VERY long time to get hot water up to the master bath.

**edit, I do also like the fact it uses standard B vent and we would not have to run special venting like most tankless require.

We did think of that also..however my wife does love her hot water, I think she could drain the tank herself with her scalding hot showers.

you are forgetting something

make one of the shower valves a tub and shower valve

install the tub spout 18'' above the floor, use it as a foot rinse

and to fill mop bucket or wash the dog

Oh what the hell was I thinking

The way you have described your water pressure problem seems to boil down the way your existing master's bathroom plumbing is set up, if you have great water pressure from other sources and your master's get the least of the pressure, you might have some diverted pipes that are off a bit and as a result are affecting your water pressure. Also the number of bends you make in routing your plumbing lines will eventually decrease the pressure for each fixture. Also, if you run 3/4" pipe, you need consider that source must be either at 3/4" or bigger then decrease as it goes to the farthest or highest point to be supplied with water and not the reverse or else you will decrease the pressure abruptly. I hope this helps.
