The details in the picture are a bit fuzzy, but it looks like the tree is in an orchard of some kind. Could it be an olive tree? FataMorgana

Dirr says: "...there are many cultivars of this tree but two which are well adapted to cold conditions are 'Carpathian' which was brought to Canada from the mountains of Poland and supposedly bears heavy crops even when temperatures reach -40°F, and; 'Hansen', an annual bearer, shells are very thick, easily shelled and the nut meats are classed as excellent..." hortster

In the shrub forum, Gardengal has ID'd this evergreen shrub/small tree as Jatropha integerrima. So, it's marginal even in 10a. Cmcgalrd01 lives in the Houston area (zone 9, maybe high 8 in some outlying areas). Sounds like it's going to be a real stretch keeping it alive without bring it indoors in the winter or providing quite a bit of protection.

Where do the 2 doors lead? Is this a master bath or hall bath or jack & jill bath? What's the purpose/benefit of 2 toilets in the first option? For me, either shower would be too tiny. Here are modifications to both options that address that: Option 1: Take out the shelf and make the shower 3x5, extending to butt into the sink on the lower wall. Because I don't get the 2 toilets thing, I'd also look at putting the 2nd sink across from the first sink (where the 2 toilets are drawn) and putting the toilet in the upper left corner. Option 2: Extend the shower to 3x5 as described above. And make the sink in the upper left longer, so it butts into the shower.
