HTP's PH1
xx-119
Phoenix 119 gallon units would more than cover your loads. The same units are also available under the Westinghouse nameplate, sometimes for less than HTP badged units.
They are not cheap (~$4K for the 119 gallon units at internet pricing), but being all-stainless will outlast most standard units by 2x, and "worth it" if you're planning to live there for awhile ( but not for the 5 year short-termers or house-flippers). It comes with condensing modulating burners with max output ranging from 100,000 BTU/hr ---- 199,000 BTU/hr.
You may even do fine with an 80 gallon Phoenix with one of the bigger burners (the same 4 options), if the gas service can handle a 199K burner, and your biggest tub is less than 80 gallons. The recovery time is pretty damned quick with a 199K condensing burner.
Bigger burners require bigger gas piping, and 199K burners in houses with ridiculously oversized furnaces and commercial cooktop kitchens can blow past the capacity of the meter or regulators, require gas service upgrades. How much "spare" capacity do you have on the meter/regulator of the existing gas service?
