If the quintessence of luxury for you is basking in a hot tub gazing up at the starry British sky with a glass of champagne in your hand, then this selection of luxury treehouses is right for you. We have specially researched the best treehouse in the UK with hot tub. What all these luxury treehouses and treehouse hotels have in common, is a private hot tub built directly on the deck, directly under the tree canopy, several meters from the ground, in total privacy. If spending a night in a cabin in the trees is no longer enough to liven you up, a treehouse equipped with a hot tub will surely make the difference. This is for us the true definition of glamping.
