When looking for the right hot tub to suit your family, a vital detail will always be the size of the hot tub.
Lengths & widths are always considered but also a very important detail is the depth of the hot tub.
On the market we see hot tubs of various depth from 100cm deep to some which are just 78cm deep
When buying a hot tub, the first priority is comfort for yourself, family & friends.
To see a difference of up to 22cm on depth would be the difference of sitting with legs stretched out or to be tucked up like a ball when really you should be unwinding & relaxing.
Of course, to reduce nearly 25% off a size would of course reduce costs but when this forsakes the primary reason for investing in a hot tub which is comfort & relaxation then it should be treated with caution.
The deeper the hot tub the more comfortable it will be, its simple.
