House in India with grand bathroom (5)
I believe the answer is:
igloo
'house' is the definition.
(I've seen this before)
'india with grand bathroom' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'with' means one lot of letters go next to another.
'grand' becomes 'g' (synonyms).
'bathroom' becomes 'loo' (loo is a kind of bathroom).
'i'+'g'+'loo'='IGLOO'
'in' is the link.
(Other definitions for igloo that I've seen before include "Ice-block construction" , "Greenland dwelling" , "cold accommodation" , "An eskimo's ice-house" , "native dwelling" .)
