Hard tp tell with out the plans or a few more details..........is it attatched to a building? Girders and number of posts, footings??
Sounds like your on the right track though,
Where did tou come up with 1900lbs though? I had one that held 350 gals x 8lbs per + the tub and people. Could well approach 3500lbs.

When you want to build solidly enough to meet strength requirements and code and not spend additional money on additional materials by guessing just to be sure, you need an engineer. This is one of those times where paying for good advice is worth it.
If you're only 18" high, why not a patio? They are much more durable than decks.
Agree ... if it's only 18" off the ground, set the tub on the ground and build the deck around it ... makes entry easier.

Read the post in this forum about deck collapse.
So what kind of beam will those joistrs sit on and how will it be supported?

Doesn't sound too good to me - 2X10 joists spanning 12' with a tub up there.
Maybe if you went with a couple of extra posts and a beam right under the tub.
You also have to consider how big your beams and other connections need to be to support this. Everything has to be done right, clear down to the posts/footings.
I think the suggestion of setting the tub on a slab and building a deck around it sounds much more appealing.

hey boss im gonna change the span to about 7'-6'' and just for kicks (because this lumber isn't heavy enough) im gonna double up 2x12's 12 in o.c. i think this will be enough beef to set my sherman tank on let me know ? thanks
I built a platform for my hot tub out of pressure treated 2x4s 16"oc with a 3/4" pressure treated plywood deck, then set that on level ground. thats it. Its been there 5 years with no problems. Its just enough to keep the hot tub off the ground. Build a deck around that.
"it's only 18" off the ground"
AMEN; heck, just pour a cheap 2 sack stiff concrete base, that'll hold it for sure.
Put a couple of $3 sq ft Italian marble tiles on the concrete if you are looking to impress anybody.
